white is the most popular color lately
Audis don't really have the dramatic beltlines, creasing, or complex curvatures/faceting in their bodywork to really play off deep-looking colors like metallics IMO, especially not when compared to the other Germans and Europeans. I think they actually made this kind of statement themselves when they released that first Audi TT in opaque Aviator Grey... my B6 is Mugello Blue Pearl, it's essentially a navy'ish pearl. Don't want to buy a pearloid color again because I'm just afraid of paint matching. It was extremely boring on my B6, but I saw an RS4 Avant in Tokyo in MGP that was really quite noble looking. I wouldn't buy it again though, nor blue really. When in doubt? Black, gunmetal, or white, for widest appeal. Stay away from dark green or champagne unless you're buying a Bentley... though I think champagne is back on the up and up, maybe someday.
