Okay, I created the thread, so it means that I must have my own picks for best paintschemes. A modern example are those green Bentley EXP GTs that raced and won Le Mans in 2003. They came and went, but not without winning what I consider to be the ultimate feat for ANY car company. They were British Racing Green and had little streaks of silver or white, and almost every shot I seen of them in 2003, each shot was a beauty. Another modern example of lovliness is the Gulf McLaren. It's a far cry from the legendary sky blue and orange of the Ford GT40, but the Gulf McLarens look pretty nice. The Rohr Porsche GT1 that I can remember had a yellow color, three dashes of other colors on the sides, and it was pretty nice. I think a year later, that yellow outside color was now white. It was a colorful machine, and probably the best to be colorful and not be something to turn eyes away from. Only Ferrari can have the Momo sponsorship. My favorite ever race car was the Momo Ferrari 333SP. Sometimes, I wish I could one day have a scale model of that red and yellow Ferrari 333SP. I've seen it on some Ferrari Challenge cars, and they look nice ONLY on Ferraris.
In terms of older models, I can remember the Coca-Cola Porsche 962C. One of my favorite car colors is red, and it's pretty cool to take a drive in. The Ford GT40 has nice colors. They are highly rememberable, and you can even get the Ford GT in the classic colors if you so chose. But to me, too many lines and a little too modern to bear the classic Gulf colors for the new GT.
