Is MixRGB ALWAYS RGB calculated? Hey guys I'm writing a Quizlet flashcard pack to help people learn and memorize how the various blending modes work within the mixRGB node.

My question is, does mixRGB always handle color inputs as RGB values and not as HSV? What I mean is, blue values in Color1 are only affected by blue values in Color2, correct? Then, when each color channel has been mixed with it's correspondent, the final resulting RGB is outputed. I know that is the way it works for most of the blending types, but are there any loopholes or exceptions that I need to be aware of?

Yes. HSV is somewhat of a crippled colour model.

Beware because most of them are display referred legacy blend modes conjured up in the dark Adobe days. The math is available in the Adobe PDF specification. They are busted up garbage in a scene referred, physical light transport system.
