When I ordered mine in July, I had 3 options:
1. unpainted flares and top
2. painted top and unpainted flares
3. painted top and painted flares
It was not possible to get painted flares and an unpainted top. That certainly may have changed.
...And, I wheel mine regularly AND have painted flares. I DO recommend it.
I don't know about black, but silver highlights the rock rash.
