Ask any artist to explain how color works, and they’ll launch into a treatise about how the Three Primary Colors

Nope.

If you ask an artist or designer about how colour works when you'll usually get is a deep sigh, followed by "it's complicated", followed by a looooooooooong explanation of some of the options presented here and a good few more besides.

(Fascinating bit of trivia: There is some moderatly persuasive evidence that some folk have more varient cone cells and can see more colours than people with "normal" vision. See http://www.post-gazette.com/stories/news/health/some-women-m... and http://www.klab.caltech.edu/cns186/papers/Jameson01.pdf).

It's usually developers who have the broken models of colour perception because, unsurprisingly, they're not trained in it :-) Artists and designers deal with multiple colour models all of the time - just go look at how many of the preferences in things like Photoshop are about managing colour... and that's just in the digital editing space.
