They say "pick like, yellow green, blue violet, and orange then TADA design it!" Then two pages later go "oh but you have to think about contrast". Then they stumble around trying to explain how to use a color scheme because they're missing a single word: value

Value is the monochrome parts of what you see. Monochrome vision is what lets you walk around and see what's in the world. It gives you form, and lets you see in 3D and read and shit. You can be totally color blind and still walk around and see what's going on because of value

Value is so fundamental that it's *very* difficult to find anyone who is missing it visually. Like, if you can't see color you can still see. If you can't see value then you're basically blind because it's just a random mess of colors with no form. But, not for designers.

Search all over the design blog world and not a single mention of value. Even though it's a central concept in all visual arts, and without it you can't render anything, I haven't ran into one book or author who uses the word or even knows the concept. Why's that important?

If design had value CSS would be value first, color second. You'd indicate the monochrome levels of every element, then simply give a color scheme assignment to each element and your design would be about 90% right. Artists always say "get the values and color can be anything."

When you are told "pick 3 colors to make your color scheme!" You're being lied to. You need to pick 3 colors, AND give each element a value from light to dark with that color to do a *real* color scheme. That solves your context. In fact, color doesn't matter.
