The {Gamma,Color}FAQ pair[1] are the traditional entries in that category, although my own experience implementing colorspace transformations is that they may be making the subject appear more complicated than it needs to be. At the same time, I’m not sure if the “falsehoods” path is the simplest here, or if an explanatory “what is” approach would be better. There’s no end to mistaken things people get confused into believing, but the fundamentals of emissive colour are just not that hard—a (mostly) linear system can only be so complicated. In that respect I think I found the introductory part of the Matplotlib colormap talk[2] to be the most helpful source on the basics. (There are difficult things about color, of course. But perceptual similarity does not in my opinion count as part of the fundamentals. And while the science of paint and light-matter interaction in general is basically endless, unless you’re doing print design or photorealistic rendering it’s probably not an immediate concern for you.)
