I used to believe that red and orange colored candies (i.e. Skittles, M&Ms, Smarties, Gummy Bears) belonged together. The yellow ones were dissatisfied with their green partners, and were always trying to hook up with the oranges. The reds could stand up for themselves, but sometimes the blues would lend a hand.
Accordingly, I never ate orange and yellow candies together. I still don't--it's that hard for me to shake.
