Illumination, or degree of illumination; as, the lightness of a room.
Absence of depth or of duskiness in color; as, the lightness of a tint; lightness of complexion.
Brightness of an area judged relative to the brightness of a white or highly-transmitting object/colour which has similar illumination.
The degree to which a color sample appears to reflect light. This attribute of color is used in the LCH (Lightness, Chroma, Hue) color model.
The lightness or brightness of a color.
having a light color
the visual effect of illumination on objects or scenes as created in pictures; "he could paint the lightest light and the darkest dark"
of a coloured material can be determined either by instrumental measurement of luminous reflectance factor, or by comparison with samples having known lightness values, e.g. the NCS Lightness Meter, which is a grey scale. Colours with the same lightness are found along the straight lines of the diagram. The positioning of these lines will vary for different hues.
The attribute of a visual sensation involving related colours according to which a colour field appears to emit equal or less light compared to a perfectly white field. Lightness can be understood as "relative brightness." Differences in lightness range from light to dark.” [2
Colour variable denoted by purity or departure from greyness. Also Value.
Property that distinguishes white from gray or black, and light color tones from dark color tones. In color space, lightness/darkness is the center axis. Also called value.
The variation of any hue along the scale from black to white.
(Brightness, reflectance, value) Position on the grey scale between pure black and pure white.
the perceptual experience of the achromatic content of a visual image, varying from light through gray to black (Thorell & Smith, 1990).
The amount of light being reflected off an object. Same as brightness. Compare to luminance and tone.
The lightness (or brightness) of a colour, independent of its hue and saturation.
The 'blackness' or 'whiteness' of the color. In terms of Color Wheel Pro, black has the lightness of -1, pure hue has the lightness of 0, and white has the lightness of 1
The attribute of visual perception in accordance with which an area appears to emit or reflect more or less light. Also refers to the perception by which white objects are distinguished from gray objects, and light from dark colored objects.
The dimension of a colour correlated with luminance. Pure white has the maximum brightness, and pure black the minimum brightness.
(n) A perceptual quality of color indicating the absolute quantity of light energy. On a gray scale, the lightest color, pure white, has the highest quantity of light. In rendering, lightness (also called value) is used to indicate the orientation of the surface to the light source.
In sensory psychology, the degree to which a light appears white (which is different from brightness, in that a dimly lit object can still appear white).
Perception by which white objects are distinguished from grey objects and light- from dark-coloured objects.
