The CIE 1976 (L*, u*, v*) color space, commonly known by its abbreviation CIELUV, is a color space adopted by the International Commission on Illumination (CIE) in 1976, as a simple-to-compute transformation of the 1931 CIE XYZ color space, but which attempted perceptual uniformity https://en.wikipedia.org/wiki/CIELUV
