A quantitative color measurement of a material. Chromaticity is determined either by the dominant wavelength of the color along with its purity or by defining its three coordinates. Its chromaticity coordinates, obtained from tristimulus values, indicate the proportion of each of the three primaries in the measured color. A chromaticity diagram or color triangle is a plot of the three coordinates.

See also Tristimulus value.
