The state or quality of being metameric; isomerism due to different bonding patterns in two substances having the same molecular formula. Contrasted with steroisomerism or optical isomerism. Also, the relation or condition of metameric compounds.
With inkjet prints, this generally refers to an effect where tones appear to change colour in different lighting conditions. Mostly noticeable with black and white prints made with coloured inksets, some tones that appear neutral when viewed under one light source will show a colour cast when viewed in a different light, e.g. daylight to tungsten light.
The phenomenon where two color samples appear to match under one light source, and differ under another. Two such samples are called a metameric pair.
A phenomenon in a scanner in which two colours that appear the same to an observer are registered as different by the scanner, or two colours that look different to an observer are accepted as identical by the scanner. Instrument metamerism is a non-recoverable error, because the input cannot be determined from the output.
An apparent change in color when exposed to differing wavelengths of light; the human perception of color.
More precisely 'illuminant metamerism' is where two (spectrally) different colour samples look the same under a particular viewing condition but different under another.
A phenomenon exhibited by a pair of colors which match under one light, but not another. An example can include colors that match indoors in incandescent light and not outdoors in natural sunlight.
An effect where a colour appears to be different in different lights. Metamerism is a fact of nature and paint s are often mistakenly blamed where metamerism is in fact the cause. The reason is that different types of light render colour differently, for example natu ral sunlight contains more blue light, whereas artificial lights contain more orange. Thus blues will appear more intense in daylight than artificial light.
is present when two objects look the same colour under one light source, but different under another light source. This is due to the objects reflecting different wavelengths under each light source. This effect often occurs with fabrics.
Variation of colour in different light sources by choice of pigmentation that causes two or more samples that match under one set of viewing conditions not to match under a different set of viewing conditions for the same person.
The tendency of color to change with the light source in which it's viewed. At BOPI, all our color is viewed under the same lighting conditions to help assure a quality product is produced.
A visual characteristic that describes a coating that appears different in colour when viewed under different lights.
Metamerism is an effect created when objects having different spectral distributions look alike under one light source but appear different when viewed with a dissimilar light source. Metamerism is most frequently seen when two colored objects match in daylight, but differ markedly in color when viewed in tungsten-filament light. This arises because the visible absorption spectra of the two objects differ significantly, although the tristimulus values in daylight are identical (the colors have the same set of color coordinates but different spectral reflectance curves)
A phenomenon exhibited by a pair of colors which match under one or more sets of conditions, be they real or calculated. Metamerism should not be confused with "flair" or color constancy, terms which apply to the apparent color change exhibited by a single color when the spectral distribution of the light source is changed or when the angle of illumination or viewing is changed.
A phenomenon that occurs when two or more photographs visually match under certain lighting conditions, but not under all lighting conditions.
The tendency of colour to change with the light source in which it's viewed. For example, two reds may appear to match under fluorescent light, but clash badly in the light of the sun.
A condition in which two objects match under one light source, but not under another.
Visual phenomenon where the colors of two spectrally different objects appear to match under a specific set of conditions. The term observer metamerism is used when two objects appear to some observers (or instruments) to have the same color, but to other observers the same objects do not match.
The tendency of color to appear different under different light sources such as fluorescent or natural sunlight.
A phenomenon exhibited by two colors that match under one or more light sources, but do not match under all light sources or viewing conditions.
Phenomenon by which color samples with different spectra appear to match under a particular type of illuminant, although under other illuminants they show a color mismatch.
The phenomenon by which colors match when viewed under one type of light (e.g.: daylight), but differ when viewed under another type of light (e.g.: fluorescent).
A condition in which a color matches under one light source but not another. The four types are Sample, Illuminant, Ob-server and Geometric metamerism.
Inks made from different combinations of pigments create matches of the same colour under one type of illumination, but when viewed under another type of illumination, the colours do not match. The phenomenon is known as metamerism and the colours are said to be metameric.
A phenomenon whereby the nature of the colour difference between two similarly coloured objects changes with change in the spectral distribution (characteristics) of the illuminant. Note 1.. Metanierism is most frequently seen when two coloured objects match in daylight, but differ markedly in colour when viewed in tungsten-filament light. This arises because the visible absorption spectra of the two objects differ significantly, although the tristimulus values in daylight are identical. Note 2.. This term is often used loosely to describe the behaviour of a single coloured object that shows a marked change of colour as the illuminant changes, but this effect is properly described as lack of colour constancy.
Two colors that appear the same under certain light conditions while differing under other light conditions.
The tendency for color to shift in hue as it is viewed under different lighting conditions.
