After evaluating both mappings, I can’t say that I see a significant difference in the shadows…perhaps a bit more abrupt transition on shadows for Colorful, but both are hitting the same max shadow value on my end. Or am I missing something? It depends on your needs and tastes, but I still consider Chroma Plus as the more disadvantaged mapping, particularly in regards to reds and magentas, which tend towards orange and desaturated respectively.
