ZCAM non-linearities
(A colour appearance model based on a high dynamic range uniform colour space)

I'm working on a implementation in .

Adjusting Chroma/Saturation/etc programmatically easily results in RGB values outside of the gamut (colors representable on screen).

To get a better idea about the problem space, I've rendered ZCAM Lightness vs Chroma in 1° Hue steps, which demonstrates the variance of the cusp positions.
