Can this also do quantizations like median cut? Does it also support colour spaces other than RGB, CIEDE (I think I saw that in the source), i.e CMYK for paint

Can this also do quantizations like median cut? Does it also support colour spaces other than RGB, CIEDE (I think I saw that in the source), i.e CMYK for paint mixing, and similar ilk? I have a few personal projects that would benefit from a library that is wide ranging in the colour space, dither algorithms (I only saw riezsma) and quantizations. Typically these are all usually implemented in different libraries :( Thanks!
