I've never been a lover of black or wheels that are too dark, I think once its in a dark wheel arch you tend to loose all the detail of the wheel and just end up with a dark circle.
However, I have been looking at that picture (above) for a week or so now and love the look of it, I just don't know if it'll suit my car, or will just end up another black circle when on the car. That's why I thought anthracite might be a good compromise, not quite as dark as black but should still show the silver bolts up well.
The black chrome will be lovely and shiney and show the wheel detail, but the bolts will be lost a bit. I hate decisions like this.
And there seems to be know one available to photoshop on here atm. ...
