Sir it depends on your personality which color and which type of modification you want, between don't go for very dark colors may be some day later you will sell it for an another good car, so paint it in simple cool colors like white, golden, silver like that. In my opinion if your hand is good on photo shop so modify bumpers there, because you will not find FX modified pictures in any catalog of any shop.
So think before taking out money from your pocket, Else you are the owner.
