Here’s an example of a single “hue” (that blue color on top) modified via lightness and colorfulness (CIECAM), with a very warm orange illuminant. It really is pretty neat, although it turns everything upside-down… lightening or reducing the colorfulness of the blue brushcolor moves it towards the orange illuminant… whilst darkening or increasing colorfulness moves it towards the original blue. Does this make sense? I’m not sure, but it is pretty lovely to play with.
