Chaplin, with a simple variation on Karl's approach...that works on almost any "tough" decision:
pick two of the three colors, flip a nickle, heads you go with one, tails the other. If you're pleased with the outcome, it is the one you preferred, but if you're disappointed, with the outcome, you really didn't want the "winner" anyway, so eliminate it, then do the same thing with the third one...lotsa luck, but it'll be a kick, no matter the color!
