I had a realization about this in college during a similar discussion of color theory:
a lot of people don’t realize their model of the world isn’t actually *real* it’s just a tool their brain made to help them make sense of things; it’s not “how the world is organized” it’s “how *I* organize the world”
I was especially shocked that artists were making this error; learning to draw forces you to confront it – you cannot draw a hand so long as you mentally label what you see as “a hand”
