Chromaticity is an objective specification of the quality of a color regardless of its luminance. Chromaticity consists of two independent parameters, often specified as hue (h) and colorfulness (s), where the latter is alternatively called saturation, chroma, intensity, [1] or excitation purity.

Graphs of the x and y coordinates of lights are called chromaticity diagrams. Chromaticity diagrams show two of the three dimensions of color, the third being luminance. This is a chromaticity diagram on which we've plotted several familiar lights.

Chromaticity is an objective, numerical specification of the quality of a color that stays constant without regard to the light that illuminates it. Color science uses chromaticity to explain how we judge the material from which the objects we see are made.

The meaning of CHROMATICITY is the quality of color characterized by its dominant or complementary wavelength and purity taken together.

The remaining two dimensions are then interpreted as the chromaticity, defined through two coordinate values. The meaning of those coordinates can be very different, depending on the used color space. For example, chromaticity may further be divided into hue (“type of color”) and color saturation.

The CIE system characterizes colors by a luminance parameter Y and two color coordinates x and y which specify the point on the chromaticity diagram.

2021年10月13日 · Chromaticity is a representation of the tristimulus values of a light (see entry on “Trichromatic Theory”) by only two numbers, computed so as to suppress via ratios the absolute intensity of the light.
