Gunmetal.
But the decals are what make that wheel so cool. Otherwise, it's just kind of a generic, old school five spoke. I don't know if there'd be a way you could reproduce them after you have them painted, but I'd look into it. I'd figure out a way to do gunmetal with light/medium gray decals.
If I couldn't do that, I'd just get them refinished so they only fix the damaged portion of the rim. I'd leave the rest of the wheel (and decals) alone.
