Black looks nice, so long as it's clean. Unfortunately, that lasts all of about 2 minutes. Red is beautiful, and the classic sports car color, but has been scientifically proven to appear 5-10MPH faster to the human eye, which is incidently why red cars get more tickets and in turn generally have higher insurance rates. White is blah, but looks good depening on the car. Silver hides imperfections/damage well, while champagne never loks dirty unless it's really dirty.
The perfect color on a car for me is Audi's Nogaro Blue Pearl, a.k.a. VW Jazz Blue, or the Blue that Nissan puts on the Skyline R34, which we don't get here. I'm just a sucker for blue.
