Bought a 2007 CTS and the color code is 41U, it was sold as a black car. I want to order new front and back bumpers prepainted, but am worried as the car does look black but in the sun it has a slight purple/plum metallic look. Almost a deep red or purple metallic flake in the paint, is this really 41U. The car doesn't look repainted, and all panels have this. Just don't want to order 41U painted bumpers and have them be pitch black when the rest of the car obviously isn't.
