I am even considering white wheels (the Speedline Corse 2120 Turanis, or Marmoras, sent over from England exclusively) on a Magnetic, but yeah, as stated above, they would quickly become the alternative anthracite color the Turanis are available in on our roads here, thanks in part to PennDOT's insistence on dumping millions of tons of brine, and salt during the winter.
Then they will turn lime green from the blasting of pollen we get in the spring/early summer.
