My
is that if you go with aftermarket wheels, you want a color that stands out, a little more "brilliant" with some pizazz, so I think that white, beige, butterscotch while being great colors on a Challenger, would be more suited for something more stock.
So.....I think the Ferrari colors, or blue, or orange. Of those colors, blue is a little more inconspicuous, red/yellow/orange being right in your face colors.
I think you would need some sort of stripe...but that's a poll for another day.
