CieLab

data class CieLab @JvmOverloads constructor(L: Double, a: Double, b: Double, referenceWhite: CieXyz) : Lab

A color in the CIE Lab* uniform color space, which represents colors in dev.kdrag0n.colorkt.ucs.lab.Lab form. This is the most well-known uniform color space, but more modern alternatives such as dev.kdrag0n.colorkt.ucs.lab.Oklab tend to be more perceptually uniform.

Note that this implementation uses a white point of D65, like sRGB. It does not implement CIELAB D50.
