White would look good. I hear that Fizik bar tape stays clean. I don't usually like to the main color of the bike, because chances are that the bar tape isn't the same shade. I only ever use colored tape (not white or black) to contrast a color on the bike, or to just stand out.
In your case the main color is red and the accents are white. White is white, so you shouldn't have any problems with it matching.
