Very, very few TTRPG sessions have artists creating art for each of them. Mine certainly didn’t before I could run genAI models locally. At most I’d grab generic, CC-licenced ambiance art, or, if the group had an artistic veined person, they’d help out with some character sheet art and such.
AI took no jobs here. And as I said, if the art is for something you profit off of, you should use an actual artist.






Uhm… No.
It depends on you doing additive or subtractive colour mixing.
Additive mixing (e.g. light, in the form of colour LEDs or similar colour sources) must utilise RGB, due to how physics works.
Subtractive mixing (such as, printing, painting, etc.) on the other hand is better off with CMY+K for higher precision, again, for physics reasons.
