Does anybody have an idea if there is touchup paint available for the Prodrive Anthracite color?

I have a pair of P7's with some minor scuffs and would like to see if there is a paint available to touch-up a few scuffs.

I'm also willing to consider an off-the-shelf touchup color at an autoparts store if there is a postive color code I could use to get a good match....kinda don't want to do it just by eye.

Anyone have experience doing this to their Prodrive Anthracite wheels themselves?

Thanks!
