I think there is some validity to color theory. I know I look better in some colors than in others. I just forget which ones. And I don't pay that much attention to it anyway. Odd as it may seem, while I enjoy dressing and thinking about clothes, I don't care that much how I actually look. It doesn't really matter except when I have something specific to do and then I want to make sure I look right for the situation, convey the right image, and am not wearing anything that would detract or distract from my overall appearance. But generally, I care more about the process than the outcome, and color theory isn't a part of the process that I care about.
