ZR2 Bumper and Fender Flare Color
 

I am looking to repaint my fender flares and I also have some rubbed off paint on the corners of the rear bumper that now shows a white color underneath, looks bad! I would like to touch up the bumper but its an odd color, its not black. I want to paint the flares black but I can't use black on the bumper. Any suggestions to match the bumper color?
