ugh. ok, relearning things I knew but forgot about. The two major color mixing systems, RGB (computers, TV sets and what you learn in science class) and CMYK (commercial printing, artists, what you learn in art class) CAN’T do everything, just a small part of the colors
I knew this – I worked for a print shop for a time – but for some reason I guess I’d hoped they’d, I dunno… improved it somehow?
There’s better color systems out there but then they get super complicated and it’s hard to find any free software that bothers using any of them.
