I think that the best color, though not my choice for my car, would be black, it is a color that stands out and gives your car a luxury though sporty feel to it, the negatives for getting black would be that it is hard to keep clean and shiny, the smallest imperfections are highly noticeable, the swirl marks really stand out, and the dirt stands out a lot. My personal choice would be white because it is at least twice as easy to keep clean as black, also because it gives your car a luxury feel, and though the dirt will stand out, it wont stand out as much as it would on a black car.
