CIE (L*a*b*) uniform color space

[4.10.2] Abbreviation: CIELAB

A transformation of the CIE tristimulus values, X,Y,Z into three rectangular coordinates (L*, a*b*) that define a space in which equal distances are more nearly representative of equal magnitudes of perceived color difference. This space is especially useful in cases of colorant mixtures (e.g., dye-stuffs, paints).
