“Color: From Hexcodes to Eyeballs” is one of the best articles on color theory and the relationship between color coding, hardware, and human color perception, that I’ve seen in a long while. Scratch that. That I’ve seen EVER!
I was already somewhat familiar with the subject, so I scrolled through the article twice, quick read it, and will have to spend even more time with it. But if you want to really understand how this part of technology works with humans, it’s the best resource that I can send you to.
