edit: note to Joofa - CIECAM02 saturation is identical

I guess an approximation to see that would be the case is to define saturation (without going into the differences between saturation and chroma, and treating them kind of interchangeably here) relative to its L value in the Lab space.

I guess what I want to say is that define saturation as equal to chroma relative to the L value of the Lab space.

Yes, that's a reasonable approximation, although for some reason Lab doesn't actually have a saturation correlate. There's a CIECAM02 calculator here .
