That can work, like i said though I prefer flat black for red cars. Flat Black will not draw any attention directly to the rims because they're not shiny, and will subtly accent the red car. Yes people do look at shiny stuff first, its an instinct :P When i have people look at cars i've detailed, i dont want them looking rims first, because chances are i've not spent most of my time on the rims, only a fraction of it. Rather they look at the rest of the car first then they take time to look at rims afterwards and notice there's not much to them
