White paint on cars always looks good on sports cars because of one reason. CONTRAST!
Sports cars typically have interesting body lines that can be hidden or detracted from with other colors because shadows don't show as obviously on reds blues or blacks, as well as on white. It makes the door, hood, trunk, and body panel seams stand out more giving more for the eyes to look at. Then theres the contrast between weels and tires, the darkness of the cabin, and any other black trim piece. White appeals to car guys and gals senses because we see more of the design on a white car. Yellow is another great color for contrast but it's too "loud" for most people. Silver would be good but often times silvers and metallic colors drown out some of lines of a car due to the viewing angle.
I used to be a black car kinda guy, but now I am a huge fan of White...although this silver is growing on me...
