About XYZ D65 and Lab

CIE XYZ is the reference space every other space is defined from. Converters use it as the common ground between formats.

CIE Lab describes lightness L and two color axes, a (green to red) and b (blue to yellow). It is device independent and is used for color differences like ΔE.

How the conversion works

We read the XYZ D65 value, convert it to CIE XYZ with the matrices from the CSS Color 4 specification and then into Lab. Values outside the target gamut are mapped by the CSS Color 4 algorithm, which keeps lightness and hue and reduces chroma.
