I like the green that comes on the newest Honda (SC model) Element, metallic red that comes on the new Civics (not Rally Red or Havanero red but those aren't bad either), Grand Prix White (S2000), Alpina White (BMW), blacks are hardest to keep clean & easiest to see swirl marks & imperfections but they look best when they're taken care of - Mercedes has a very dark black, Toyota Matrix has a nice metallic black along with BMW's Black Sapphire Metallic.
