No, the white ones are literally painted white. They were on the white package cars that had white door trim and white wheels. From your pic, your wheels look silver.
Worst case, if you strip them and hate it you can paint them whatever color you want, cause they're ready to paint.
Mine have been bare metal since march and I only washed them maybe 4 times, and it's been parked outside. They still look polished. I'm going to get some polish and a mothers powerball and see if I can make them better, I'm sure they've dulled a little since I first did it.
