I agree. with what you said. BUT, truth be told, funky color combos can be a distraction! If I'm watching a dancer & she's wearing an odd color combo, I think my mind wanders thinking 'What is up with THAT??'. I guess it also depends on the distribution of the colors....like in your purple & red example: if one is simply an minimized accent color, I might not trip out aobut that but if the colors seem to be in a battle to dominate then.... ;-)
