What color should the spindle, backing plate pretty much the whole spindle be? I have it at the powder coated and was going to do it the same chassis black but now I'm haveing second thoughts. Should it be the natural metal color? And also the backing plate? Need help quick!

I did Silver for the backing plate, all the rest black.

The spindles were not painted, so they were natural grey cast iron.
The backing plates were silver zinc, and the caliper brackets were gold zinc.
