When I went to makeup school 25 years ago, I was taught some color theory - the basics. At the time there was much focus on defining people as "winter, spring, summer or fall" and choosing the right colours from them based on that. As I rather quickly ended up in fashion industry make-up, colour theory did not seem as important to me at the time. I didn't think twice about it really, seeing as a lot of make-up choices could be either rather bold, or completely in disregard of what actually "suited" the model in an every-day kind of way.
Knowledge regarding matching foundations and concealing obviously came to me over the years through experience, as did choices of eyeshadow colors to match or contrast eye-colors but I must admit my interest in (and respect of) color theory is very recent. Partially due to the wonderful attempts of make-up artist Kevin J Bennett to educate his fellow make-up artist colleagues by stressing the importance of mastering color theory. And also though his many posts on Facebook and sessions at various IMATS, trade shows around the world.
I've found it's a great way to define and arrange my color-knowledge, to finally understand WHY some colors look good together, other than just "knowing" they look good!
