I have a '75 911S that was originally a light yellow, probably similar to this color. It's been repainted black and the paint is bad. When I do get around to fixing the paint I will certainly return it to that original color, but I think it will look better in general on an old Porsche.
BTW, I talked to the original owner. He said he painted the car black in 1984 because of too many speeding tickets in the car when it was yellow...
