unless you are speaking of a bumper off of a Honda with the OEM paint still left on. But noone takes replaceement parts and paints them to OEM color if thats what your asking. Honda will do it for you, and a paint shop can get the color close, just be sure to get an epoxy clear coat, with mulitple coats. Closest to OEM there is. But its to risky for return claims for someone to expect a flawless painted fender for any resonalble price.
But you could always just become a ricer and make your car now "black "by not painting your parts <--wouldnt suggest
