The L* (perceptual brightness) value of this color in the range [0,100].
The u* value of this color. Forms a Cartesian coordinate pair with v* to represent the four unique colors of human vision (red, green, blue, and yellow).
The v* value of this color. Forms a Cartesian coordinate pair with u* to represent the four unique colors of human vision (red, green, blue, and yellow).
A CIELUV (CIE 1976 L*,u*,v*) representation of a color. Intended to be a perceptually uniform space. Derived from CIEXYZ. Colors are defined relative to a standard observer. Compared to CIELAB, CIELUV is considered better for emissive, self-illuminated colors (such as those on a monitor).
