Related to chrominance: chrominance channel


The difference between one color and a reference color of the same brightness and chromaticity.

[Blend of chromo- and luminance.]


1. (General Physics) the quality of light that causes the sensation of colour. It is determined by comparison with a reference source of the same brightness and of known chromaticity
2. (Broadcasting) the information that defines the colour (hue and saturation) of a television image, but not the brightness
[C20: from chromo- + luminance]


(ˈkroʊ mə nəns)

the difference in color quality between a color and a reference color that has an equal brightness and a specified chromaticity.
