I think that the most stunning colors on cars are the ones on the TVRs, I once saw one at a car show, and it was absolutely amazing, it really does change color when you move. Absolutely stunning (wouldn't look good on a Ferrari though, IMO, nothing beats red on a Ferrari!).
It is TDF blue indeed, saw an identical color spec car while in Maranello. The display lights matched with digital photography processing makes the color appear lighter than it is in the pic.
