CIELUV
In Colorimetry, the CIE 1976 L,u,v* colour space, also known as CIELUV is a Colour Space defined by the International Commission on Illumination in 1976, as a simple-to-compute transformation of the 1931 CIEXYZ colour space, but with attempted perceptual uniformity.
It was based on the 1964 CIEUVW colour space.
CIELUV was created alongside CIELAB in the set of CIE 1976 Uniform Colour Spaces. CIELAB is better suited for colour displays, while CIELUV is better for surfaces and dyes.
Although additive mixtures of different coloured lights will fall on a line in CIELUV's uniform Chromaticity diagram, called the CIE 1976 UCS, they will not fall on a line unless the mixtures are constant in Lightness.
