To acquire color; to turn red, especially in the face; to blush.
The character of a surface that is the result of the response of vision to the wavelength of light reflected from that surface.
A broad term used to describe the hue of the mead. Meads vary from nearly colorless to gold to deep burgundy reds with pink, and all the shades of red and gold in between. Clarity and color are part of the visual experience of enjoying meads.
The color scale is used to describe the color tones of a gemstone. For diamonds, the color scale ranges from D, meaning completely colorless, to Z, which indicates a distinct yellow cast. As the scale moves from D to Z, it indicates increasing levels of yellow and brown tone. For color gemstones, the color is measured by tone and hue. Color is the most important criteria in determining the value a colored gemstone. More important than clarity and cut, even subtle differences in hue can correspond with marked variations in valuations
The aspect of a light source that can be described in terms of hue, brightness and saturation; the specific property of objects seen as red, yellow or blue as opposed to black, white or gray.
(chroma) Color, chroma, and hue are the three most common terms used to indicate the tonal values as perceived by the eye.
On computer screens electron beams light phosphors of three different frequencies: red, green and blue. The color palette is divided into hues of red, green and blue (RGB). In markup languages color can thus be described with values indicating more specific frequencies within these three basic ranges. In HTML there are three methods: reserved keywords (such as "black" and "red"), the 16-base hexadecimal notation and the 10-base RGB system. Each Colour consists of a combination of these, and each hue is noted in terms of 2 digits, using both the numbers and alphabetical characters of the hexdec system. NB: There are zeros in the table below (not O's = oh's). The second row shows the syntax for indicating a color. End the hexdec sequence in quotation marks. The hexdec number must be preceded with the hash (#). R zone G zone B zone"#" Red"#" Green"#" Blue"#" In HTML values should preferably be marked in quotation marks (this is optional, but good practice, as HTML authors will probably also author XML, which does require quotation marks). In CSS values are not marked in quotation marks.
The subjective interpretation by the human eye and nervous system of electromagnetic radiation in the 380 to 760 nm band (visible light). Energy at the short end of the visible spectrum (c. 380 - 450 nm) produces the sensation of violet, while the longest visible waves (c. 630 - 780 nm) appear red. Between these two extremes, the eye sees blue (c. 450 - 490 nm), green (c. 490 - 560 nm), and orange (c. 590 - 630 nm). Infrared light ("below the red") is that area of the spectrum adjoining the long wavelength end of the visible band. Ultraviolet light ("beyond the violet") adjoins the short wavelength end of the visible band. Also, a function of the luminaire specified by color and saturation data, or by filter position data. Hue is the subjective appreciation of the dominant wavelength of a light source; the attribute of color perception by which different parts of the spectrum are distinguished (red, orange, yellow, blue, violet, and purple). Saturation is the subjective appreciation of purity, a relation of the intensity of the dominant wavelength to all other wavelengths (defined by terms such as deep, pale, light dark).
The basic color of diamonds from white to yellow, measured on a scale from D through Z.
Response of the eye to different wavelengths of light. Ultraviolet 400 nm, violet 400-424 nm, blue 424-491 nm, green 491-575 nm, yellow 575-585 nm, orange 585-647 nm, red 647-700 nm, infrared 700 nm. Maximum visibility occurs at 556 nm.
The first step in assessing a wine; color is one of the primary characteristics we use to determine type and quality. Color is drawn mostly from grape skins during the fermentation process, when the skins remain in contact with the juice. As well, older wines lose vibrance of color: whites get darker and reds get lighter, although color can not be relied upon to determine the quality of a wine.
The aspect of any object described by hue, lightness,and saturation of electromagnetic waves within the wavelength spectrum visible to the human eye.
Color has three measurable properties: hue = the name of the color; value = the degree of lightness or darkness; intensity = the degree of brightness.
A key determinant of a wine's age and quality; white wines grow darker in color as they age while red wines turn brownish orange.
The physics of color is made up of a subset of the electromagnetic spectrum which, when combined, shows as white. Human eyes are physiologically adapted to view such rays, when they are reflected from objects, as colors. On CRT screens (such as computer or TV screens) electron beams light phosphors of three different frequencies: red, green and blue. The color palette is divided into hues of red, green and blue (RGB). Markup languages In markup languages color can be described with values indicating more specific frequencies within these three basic ranges. In HTML there are three methods for describing a color: reserved keywords (such as "black" and "red") the 16-base hexadecimal notation the 10-base RGB system. In Graphics application programs there are typically be more methods available for describing color hues than just the RGB method, such as CMYK and HSB.
A property of quarks and gluons. Gluons can exchange color between quarks and other gluons. This process is the origin of the strong force. It has nothing to do with the color perceived by the human eye.
That property of an object which is dependent on the wavelength of the light it reflects or, in the case of a luminescent body, the wavelength of the light it emits. If, in either case, this light is of a single wavelength, the color seen is a pure spectral color, but, if the light of two or more wavelengths is emitted, the color will be mixed. White light is a balanced mixture of all the visible spectral colors.
a visual attribute of things that results from the light they emit or transmit or reflect; the visual response to the wavelengths of light, identified as red, blue, green, etc.; primary and secondary colors; warm, cool, and neutral colors, color value; hue; and intensity.
(1) red or black; sometime method of referring to suits: spades and clubs are the black suits, hearts and diamonds are the red suits;(slang) any one of the four suits.
Is an adjustment in the user menu for setting the intensity of colors. When color is set correctly the intensity of blue is the same as its intensity in white.
The human perceptual response to different wavelengths of light impinging on the photoreceptors in the retina.
Color is one of the Four C's used to determine a diamond's quality and ultimate value. It is measured using a "Master Set" of diamonds, already evaluated for their grade along the color scale.
(a.) Of an object, a visual property that depends on wavelength; (b) an arbitrary name assigned to a property that distinguishes three kinds of quarks.
The color or combination of colors exhibited in precious opal; does not take into account the color of the stone itself, but only the play of colors within the stone. If one color is very predominant in an opal then the color of that opal will be that color e.g. an opal that is predominantly red with a little blue will be classed as red. If two colors are predominant (e.g. red and gold), then it shall be classed as red/gold. The minor colors will be listed in the description. If an opal has three dominant colors then it is classed as a multicolor. Back
Myoglobin, which contains iron and is the storehouse for oxygen in living tissues, is the principal heme pigment influencing meat color. More myoglobin in meat produces a more intense red color. Breast muscle or white meat contains less myoglobin than dark poultry meat.
(colour) : the human eye perception of the electromagnetic radiation within the human visibility range (approximately from 380 nm to 760 nm; the visible spectrum). Most light sources are not pure spectral sources (single radiation wavelength); rather they are created from mixtures of various wavelengths and intensities of light. To the human eye, however, there is a wide class of mixed-spectrum light that is perceived the single color, same as a pure spectral color.
1. in heraldry, any hue which is not a metal. 2. a flag carried by a military unit as a unit or national identification. Military forces of English-speaking countries often carry a pair of colors, one national or royal and the other of the unit itself. As distinguished from a standard, a color is used by foot units. French - drapeau Spanish - bandera (de regimiento) German - Fahne or Truppenfahne Italian - bandiera Russian - znamya Danish - fane Dutch - vaandel (Netherlands), vlag (Belgium) Swedish - segerfanan Romanian - drapelul de lupta
One of 128 values obtained from a hue-luminance combination which is stored in a color register.
a shade, such as red or green that possesses hue.
Cheques. The color of a cheque denotes its value. Standard cheque colors are white ($1), red ($5), green ($25), and black ($100). Higher denomination, or odd denomination, cheques are also color-coded, but there seem to be no standards.
One aspect of appearance; a stimulus based on visual response to light, and consisting of the three dimensions of hue, saturation, and lightness.
An element of design that identifies natural manufactured things as being red, yellow, blue, orange or any other name that identifies their hue.
Colors of food products are based on different types of naturally occurring compounds. For example, the green in green beans is from chlorophyll and the red in tomatoes is from a class of color compounds called cartinoids.
Measured against a platinum-cobalt standard (PCU or Pt-Co units), can give an indication of the relative amount of dissolved organic matter in the water. High coloration, or "bog stain" as it is referred to, is usually caused by runoff from wetlands or forested lands. At high values, color may interfere with the expected phosphorus - chlorophyll - Secchi relationship of a lake. In general, values between 0-20 are considered clear, 21-50 are considered moderately colored, 51-100 are considered highly colored, and values greater than 100 can be considered very highly colored. Based on data from the ecoregion reference lakes color begins to influence the phosphorus - chlorophyll - Secchi relationships above about 50 Pt-Co units, and may strongly influence the relationship above 100 Pt-Co units. In highly colored lakes, transparency and chlorophyll values are often lower than expected based on the phosphorus values. Learn More...
8, 16, 24 or 32-bit color, which is equal to 256, thousands of colors and millions of colors respectively. 8 bit color can be called indexed color because it uses a specific color table (the "palette") of only 256 colors. 16, 24, and 32-bit color is commonly called RGB (red-green-blue) color. File types like GIF, Pixelpaint and Macpaint can only be 8-bit color, while other file types like JPEG and TIFF are all-inclusive.
The amount or presence of body color in a diamond. Color is an important factor to beauty, rarity, and value because it is something a consumer can see without the aid of equipment. The absence of color in diamonds is most rare and highly prized. Most diamonds mined in nature have traces of yellow, some brown or gray. When deeper colors appear, these are called fancy color diamonds.
Color is produced when light strikes an object and then reflects back to your eyes. It has the following qualities: hue, which is the name of a color; intensity, which is the purity of a color; and value, which is the lightness or darkness of a color.
One of the Four C's, color refers to the degree to which a diamond is colorless. Diamond color is a significant factor in determining value. The color scale ranges from D to Z, from colorless to light yellow.
Colour is defined as is either a keyword or a numerical RGB specification. There are 16 defined color name keywords: aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, purple, red, silver, teal, white, and yellow. For numerical RGB specifications hexidemical values are used and always preceed the # symbol - #RRGGBB. A shorthand value of the RGB specification is also used - #RGB.
One of the "4 C's," color refers to the presence (or absence, ideally) of a particular color in a diamond. The scale ranges from D (colorless) to Z. An ideal diamond will have as little color as possible. The closer to white or "colorless" the stone appears, the more valuable it is. Fancy colors are not included in this color scale and are considered extremely rare.
The element of art derived from reflected light. There are three properties of color: Hue, value, and intensity.
a phenomenon of light (as red, brown, pink, or gray), element of design, hue or visual perception that enables one to differentiate identical objects.
Term used to describe the base color of a pearl.
(physics) the characteristic of quarks that determines their role in the strong interaction; each flavor of quarks comes in three colors

used to set the color of any number of things, including objects and light sources. ( Tutorial) ( Language Reference)
Wavelengths of light perceived by the eye.
Color is a grade that indicates the color of the stone. The scale ranges from D, completely colorless, to Z, which refers to an easily noticed yellow tone. The higher scale, the more distinct the stone's yellow or brown cast.
Color Describes a colour with 8 bits each of red, green, blue and transparency.
The color in digital imaging is based on bits. The more bits per pixel an image contains, the higher the resolution (quality). The trend in digital cameras is to offer as many bits per pixel as possible. Although this allows the photos to be crystal clear, it also takes more memory per image and will only print on compatible printers. 1-bit color: is the lowest number of colors per pixel that an image can have; picture is black and white. 8-bit color: each pixel has eight bits assigned to it. This allows the image to have 256 colors or shades of gray. 24-bit color: each pixel has twenty-four bits assigned to it. This allows the image to have 16.7 million colors. Eight bits (or one byte) is assigned to each of the red, green and blue components of each pixel. 32-color: This represents true color and is the lowest color scheme to bring all the colors of everyday life into a photograph. It offers over 16 million colors. Higher color schemes are available, however they may encounter compatibility trouble (many machines read only a certain amount of different colors).
An element of art derived from reflected light. The sensation of colors aroused in the human mind as vision responds to various wavelengths of light. The three properties of color are hue, value, and intensity.
A concept created by the human brain to help interpret spectral information received by the human eyes. Applied to photons in a band as well as a monochromatic beam.
The effect of light of varying wavelengths on the human eye. In paint, color is created by various tinted pigments.
The basic characteristic that differentiates the six varieties of quark.
The visual sensation of human response to seeing certain wavelengths of light. To see color, there must be a light source illuminating objects that absorb or reflect the light to the human eye. The color or colors seen depend on the quality of the light source, the objects light absorbability or reflectivity (the color of the object), and the sensitivity of the human eye.
Diamonds are graded on a color scale established by the Gemological Institute of America (GIA). The scale ranges from D (colorless) to Z. Hues such as pink, blue, green, yellow and red appear in the class of gems known as Fancy diamonds.
Diamonds are graded on a color scale from D (Rarest White) to Z (noticeably Yellow) established by the Gemological Institute of America (GIA). Fancy colors are not included in this color scale and are considered extremely rare. Fancy colors refer to diamonds with hues like pink, blue, green, yellow, and very rarely red.
An element of art defined as the effect of light reflecting from an object onto the eye.
A grade measuring evaluation that describes the body color of a diamond. This color scale ranges form D (absolutely no hints of color present) to Z (an obviously yellow or brown diamond) (See 4'Cs of buying a diamond)
Of the seven basic tinctures, five are COLORS. These are: Azure, Gules, Sable, Vert, and Purpure. (Blue, Red, Black, Green, and Purple, respectively).
Most diamonds appear colorless, but may actually contain very faint traces of yellow or brown. The less color a diamond has, the more rare, valuable and beautiful it is. The color scale describes the degree of color in a diamond, starting with the letter D (completely colorless) and increases all the way to Z (heavy brown).
The human eye can differentiate about 350 000 different colors under normal sunlight conditions, but only 128 gray levels. If the colors only have different saturation values, the eye can only differentiate 16 yellow tones and 23 different shades of red or violet. A color scanner reads every pixel of a color original with 256 levels each of red, green and blue. This gives 16.8 million different color shades (3 x 8 Bit 256 x 256 x 256).
Refers to the character of a surface derived form the response of the vision to the light reflected from that surface.
the various visual phenomena that are the results of the reflection or absorption of light by a surface. Color has three properties: hue, value, and intensity.
The visual response to the wavelengths of light, identified as red, blue, green, etc. Color: primary and secondary colors; warm, cool, and neutral colors, color value; hue; and intensity. Color depends on light because it is made of light. There must be light for us to see color. A red shirt will not look red in the dark, where there is no light. The whiter the light, the more true the colors will be. A yellow light on a full color painting will change the appearance of all the colors.
1. An object representing the intuitive definition of a color, such as black or red. 2. A Lisp object that represents a color.
The attribute of visual experience that can be described as having quantitatively specifiable dimensions of hue, saturation, and brightness or lightness. The visual experience, not including aspects of extent (e.g., size, shape, texture, etc.) and duration (e.g., movement, flicker, etc.).
Scanner sensors pick up and record the colors red, blue and green. These three colors, in different combinations, form every other color.
LEDs are designed to give off a specific color emission. The dominant wavelength is a quantitative measure of an LED color as perceived by the human eye and is usually measured in nanometers (a billionth of a meter). In order to specify an LED, you must specify the color or dominant wavelength range required for your application. Some applications may have color constraints in order to meet specific government specifications or regulatory guidelines.
A generic term referring exclusively to all colors of the spectrum, including white and black. Color is described by three properties: hue, lightness and saturation. (1) Hue (color, character, dominant wavelength): blue, green, red, etc. (2) Lightness (brightness, reflectance, value): position on the gray scale between pure black and pure white (3) Saturation (purity, grayness, cleanliness, muddiness, chroma): purity or intensity of color.
Grading color in the normal range involves deciding how closely a diamond's body color approaches colorlessness. Most diamonds have at least a trace of yellow or brown body color. With the exception of some natural fancy colors, such as blue, pink, purple, or red, the colorless grade is the most valuable.
The body tint of a diamond. The less color seen in a white diamond, the more valuable it is. The opposite is true for "fancy" colored diamonds, which increase in value as the intensity of color increases.
A combination of hue, value and chroma.
This may range from white to brown and is defined by a standard nomenclature ('grading scale'), ranging from D to Z.
grading A grading method system by GIA used to determine the colorlessness of white diamonds.
When light is reflected off an object, color is what the eye sees. The primary colors are red, yellow and blue. The secondary colors are orange, purple and green.
is a powerful element in communicating symbolic meanings, emotions to attract the reader's attention. It is the visual sensation produced in the brain when the eye views various wavelengths of light.
Pigment that makes a hue. Sensation produced by the effect of waves of light striking the retina of the eye. The visual sensation dependent on the reflection or absorption of light from a given surface. Different colors are produced by rays of light having different wavelengths
a quality of light, depending on its wavelength. Spectral color of an emission of light is its place in the rainbow spectrum. Perceived color (or visual color) is the quality of light emission as conveyed by the human eye, combining the impressions of 3 types of light-sensitive cells which the eye contains. Perceived color can be the response to certain combinations of spectral colors, e.g. brown responds to green and red (or blue, yellow and red).
Aspect of paint film that depends upon the spectral composition of the incident light, the spectral reflectance or transmittance of the film, and the spectral response of the observer, as well as the illuminating and viewing geometry.
One of the traits used in grading your diamond. Color is graded on a scale from D (colorless) to Z.
While color can simply refer to an attractive wine and how it looks in the glass, it also plays an important role to the variety of wine itself. Obviously if a chianti is very very light red, almost pink, something is wrong, or if a pinot grigio is more of a brownish color, again, something is wrong.
Color is the effect produced on the eye and its associated nerves by light waves of different wavelength or frequency. Light transmitted from an object to the eye stimulates the different color cones of the retina, thus making possible perception of various colors in the object.
One of the most important factors in classifying pearls. While pearls traditionally were thought mainly to be white (with some exquisite pinks and blacks also well-known), nowadays pearls come in all colors. The most common are still white (which are often bleached at source), and there are many shades of natural color pearls (ranging from peach to champagne to rose to purple). And dying techniques have advanced to the point that pearls are now available in any color of the rainbow, some of which are quite dazzling. Normally, the dying process involves soaking the pearls for a day in dye until it permeates the inside of the pearl; then baking the color in so it won't rub off or fade.
In a red-black tree (see red-black tree), a property of a node, either red or black. Node colors in a red-black tree are constrained by rule 1 (see rule 1) and rule 2 (see rule 2)
Though not always talked about by The Wine Dictator, the color can tell a story about a wine. As a wine ages, its color will change; red wines will fade toward orange and/or pink, and white wines gain color, becoming golden.
Visual sensation dependent on the reflection or absorption of light from a surface. An element of art with three properties: (1) hue, the color name, e.g., red, yellow, blue; (2) intensity, the brightness and purity of a color, e.g., bright red or dull red; and (3) value, the lightness or darkness of a color.
A letter grade indicating the whiteness of a given diamond. D is the highest possible grade, indicating colorlessness, and is very rarely seen. Diamonds graded G to H are nearly colorless, while a grade of I to K indicates a light white color.
1. integral pigment added to a concrete mix design. 2. as relates to manufactured cast stone, the colour choice is separate from choice of hue and tone which are not controllable and vary widely.
a visual attribute of things that results from the light they emit or transmit or reflect; "a white color is made up of many different wavelengths of light"
the relative position of a diamond's body color on a colorless to light yellow scale, denoted by letters (i.e., D to Z, where D is colorless and Z is light yellow) on the GIA color scale, or by numbers (i.e., 0 to 10, where 0 is colorless and 10 is light yellow) on the AGS color scale.
The color of a wine is merely an observational characteristic, and does not necessarily have any merit attached to it. Determining the color should be done against a white tablecloth in natural light, or as close as possible to a natural light source. See the “Common Wine Colors” tutorial for more detailed description for each wine type.
Measurement scale used in describing the level of tint in the body color of a diamond. "D" color represents the absence of color, and is the most desired. Tint levels progress through the alphabet as color levels increase.
Diamonique® stones are an E on the color scale – a perfect blue-white stone.
The aspect of the appearance of an object dependent upon the spectral composition of the incident light, the spectral reflectance or transmittance of the object, and the spectral response of an observer.
A grade given to a diamond to describe the color tones of the stone. The color scale ranges from D, meaning completely colorless, to Z, which has a distinct yellow cast. As the scale moves from D to Z, it indicates increasing levels of yellow and brown tone.
Diamonds are graded on a color scale established by the Gemological Institute of America (GIA). Fancy colors refer to diamonds with hues like pink, blue, green, yellow, and very rarely red. Fancy colors are not included in this color scale and are considered extremely rare.
The GIA (Gemological Institute of America) has established an industry-accepted color grading system that rates diamonds with alphabetical letters ranging from D (no color), the most expensive through Z (yellow). If you plan to mount the diamond in a platinum or white gold setting, you may wish to choose a color from D through H. Colors below H have a slighly yellowish hue which appear more yellowish in platinum or white gold settings and are therefore best suited to yellow gold settings. See additional information on Color.
A term used to describe the natural body color of a diamond. The more colorless a diamond, the rarer and more expensive. With a range from D (least color) to Z (most color). Color ratings of G through L are the most common.
Important property used in the evaluation of a gem, particularly the diamond. Interestingly enough, the quality of a gem may be measured based on either the presence or the absence of color.
A standard deck has two colors: Hearts and Diamonds are red, Clubs and Spades are black.
The individual components of white light as perceived by the human eye. Color monitors use the three basic components of color to which the human eye responds: red, green, and blue. The final color seen on the screen is created by mixing these primary colors.
White is just one of the many natural colors of cultured pearls. Akoyas range in hue from rose, cream and gold to silvery white and blue-gray. South Sea pearls go from purest white to deepest gold. Tahitian pearls cover the spectrum from silver and black to peacock green, purple and deep blue. Freshwater pearls have the widest range: pales of white, rose, pink, peach and lavender to deeps of burgundy, blue-gray and bronze.
White, red, and rosè¬ each of which has its own spectrum from light to dark. It is the skins of the grapes that give a wine its color. During the wine-making process, the longer the juice is in contact with the skins, the more color will be imparted to the wine. A pink or rosè ·ine is made from red grapes but is only allowed brief contact with the skins.
The color of wine tells us much about its origin and wine making. Deeper colors usually relate to longer wine making practices and higher quality wines. Red wines range from Blue-Red, through Red and as they age towards Orange (or brick) Red. White wines range in color from clear to deep golden, with hints of greens common in lighter wines. As whites age they tend to turn towards brown.
A quality that is sometimes overlooked by novice wine drinkers, a wine's color gives an indication of its BODY, its VARIETAL makeup, and the methods of its production. Ideally, no matter what its hue, a wine should be limpid and clean-looking, with no murkiness.
A generic term referring inclusively to visible lightwaves in the spectrum, and white and black. Color is described by three properties: hue, lightness, and saturation
Every face has it's own color. The six colors usually are: white, yellow, orange, red, green and blue. The blocks can be labelled by combinations of colors, for example BY would mean the blue-yellow meson, and RYG is the red-yellow-green baryon. Naturally, opposing colors can never appear on one block. Note that the colors are for labelling purposes only! Solving the cube isn't about getting the colors right, but getting the blocks next to the blocks so that the colors match up. There is a subtle difference which I'll explain later.
The reflecting of light in a narrow wavelength band within the visible spectrum on a given object as viewed by an observer. Hue.
The general hue of a diamond, graded according to a relative lack of color - from completely colorless (D) to light yellow (Z).
A quality/value evaluation category used to describe the color of a pearl. Although color is not particularly an indicator of quality, generally creamy/yellow hues are less valuable than other pearl colors.
One of the 4 c's, color means different things for different stones. In diamonds, the ideal color is D colorless and runs through the alphabet to Z yellow. For colored stones, on the other hand, each type has a very complex grading system (see our color stone guides for a particular type) Color, of course, is one of the most important value factors for all gemstones.
Measured in color units that relate to a standard. A yellow-brown natural color is associated with lakes or rivers receiving wetland drainage. The average color value for Wisconsin lakes is 39 units, with the color of state lakes ranging from zero to 320 units. Color also affects light penetration and therefore the depth at which plants can grow.
The perception of the frequency (or wavelength) of light, and can be compared to how pitch (or a musical note) is the perception of the frequency or wavelength of sound.
Color (or the absence of color) is one of the most noticeable characteristics of a diamond. Color grading, using the GIA scale, ranges from D to Z, with D being colorless and Z being heavily (usually yellow) colored. Colorless stones (designated D, E, and F) command the highest prices. (For more information, see our Diamond Grading article.)
Color is the one of the most important characteristics in appreciating gemstone. Color in gemstones is described by hue, saturation and tone.
The visual sensation dependent on the reflection or absorption of light from a given surface. The three characteristics of color are hue, value, and intensity.
an element of art with three properties: (1) hue or tint, the color name, e.g., red, yellow, blue, etc. (2) intensity, the purity and strength of a color, e.g., bright red or dull red; and (3) value, the lightness or darkness of a color.
1) Used to refer to perceived qualities that result from the response of vision to the wavelength of reflected or transmitted light. 2) Describes images that have hues, as opposed to black, white and gray tones only and the processes used to make them.
Element of art that comes from reflected light. The sensation of color is aroused in the brain by response of the eyes to different wavelengths of light. A color has hue (color name), intensity (strength) and value (lightness and darkness).
Different varieties of mollusks produce specific natural colors. Although color is usually a preference of the wearer and not an indicator of quality, generally creamy/yellow hues are less valuable than other pearl colors. Our Freshwater pearls develop into a wider range of colors than any other type of pearls. Colors include a range of light and intense deep colors such as white, pink, peach, tangerine, lavender, plum, cocoa, and more.
Describes the "yellowness" of a stone. The color scale ranges from D (colorless) to Z (deep yellow)
That which the eyes sees when light is reflected off an object.
Color is a quality factor used to describe the color of a pearl.
The color grade of the diamond.
The term color actually refers to the absence of color in a diamond. A diamond acts like a prism letting light pass through, refracting back to the human eye, into a rainbow of color. The color scale breaks up the subtlety and various grades of a diamond's color from purest white to yellow and brown.
The color of the rind and the interior of any cheese is an indication of its variety, condition and quality. In all cases, the color should be characteristic of the cheese type. Cheese colors naturally range from snow-white to deep yellow. Orange cheeses, such as Cheddar, are colored with annattoâ€”a tasteless, odorless natural vegetable dyeâ€”during manufacturing.
When light strikes an object and is reflected back into the eyes part of the spectrum of the light is absorbed by the object. The remaining elements of the spectrum which then hit the eye constitute the color of the object. See the Color Theory and Mixing forum
Color refers to the "look" of wine. That is, the actual color (red, yellow, brown etc.), its opacity(clear, cloudy), and other characteristics. If the color of a wine is wrong for that wine, it may be bad or not yet aged enough.
(n) The perceptual quality of a surface that results from the combined response to lightness, hue, and value. Hue is often confused with color since the names of hues (e.g., red, purple, yellow, etc.) are used as the primary classification terms for color.
Light waves that reach the viewer's eye by transmission (through an object between the viewer and the light source) or by reflection (when light waves bounce off an object). All substances, whether transparent or opaque, absorb some wavelengths while letting others pass through or bounce off. A red apple looks red because it absorbs all colors in white light except red, which it reflects. White objects reflect all and black objects absorb all light waves (at least in theory).
Any coloring matter, dye, pigment or paint. The primary colors are red, yellow and blue which when mixed in various combinations produce the secondary colors. Black, white and gray are often referred to as colors although black is cause by the complete absorption of light rays and white by the reflection of all the rays that produce color and gray by an imperfect absorption of all these rays.
Aspect of object appearance distinct from form, shape, size, position, or gloss that depends upon the spectral composition of the incident light, the spectral reflectance of transmittance of the object, and the spectral response of the observer, as well as the illuminating and viewing geometry.
A property of light determined by its wavelength.
1. The perception of the different wavelengths of light reflected off opaque objects or transmitted by translucent objects. 2. A property of light that depends on wavelength.
Color (or colour, see spelling differences) is the visual perceptual property corresponding in humans to the categories called red, yellow, white, etc. Color derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra.
