Detect whether T is an L*C*h° color.
Detect whether T is a L*a*b* color.
A CIE L*C*h° color, parameterised for component type and white point. The LCh color space is a Lab cube color space, where instead of cartesian coordinates a*, b*, the cylindrical coordinates C* (chroma) and h° (hue angle) are specified. The CIELab lightness L* remains unchanged.
A CIE L*a*b* color, parameterised for component type and white point.
This module implements the CIE Lab and LCh _color types.
Lab is full-spectrum, absolute, vector _color space, with the specific goal of human perceptual uniformity.
