I've always been a fan of cerise myself. I definitely mix up colors, usually no more than 3 colors though. I have found that tying in a little bit of flash can help from time to time, I think it has made the difference more than once. My favorite combos are shrimp pink/cerise, flame/cerise, shrimp pink/white. Sometimes I throw a little smidge of chartreuse in too. Don't know if that helps, just what I've found.
