Red and blue would be cool, but why add the yellow in there? The red and blue they could pull of a kind of Superman theme thing. I think it'd be cool, throw a superman logo on the hood or something, it'd be a cool theme type of car. Personally, I'd have to go for a Green Lantern theme if I was gonna do some crazy superhero theme, but I may be kinda biased since I have a Green Lantern tattoo on my right arm.
