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.

2022年9月27日 · Chromaticity is a property that characterizes the color quality of an object seen by the human eye and gives a measure of how well an object is seen by the human eye. It is independent of the brightness and so is different from luminance where brightness is indicated.

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.

Chromaticity is a three-coordinate value that is mapped onto a color space, where light spectra are numerically described according to the stimulus of the eyes by light. This is done by the use of three color-matching functions that correspond to the peak wavelengths of …

Chromaticity refers to the quality of a colour that sets it apart from white, grey, or black. The chromaticity of different colours is often described by chromaticity coordinates that define where a colour appears within a colour space.

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.

2023年12月26日 · Chromaticity is the objective specification of the quality of color that remains consistent regardless of the illuminating light. It is a fundamental concept in color science that helps explain how we perceive the color of objects.
