Scuderia grey wheels vs. Challenge grey

I'm considering having the Challenge wheels on my F430 repainted, currently they're the "regular" silver and I'm considering either the dark Challenge grey that I've seen in some pictures or else the Scuderia grey.

Does anyone have side-by-side pics of Scuderia wheels and grey Challenge wheels? Is it the same colour?

 

Nobody huh? I've done a bunch of forum searches that unfortunately turned up nothing, I would've thought that with the incessant "Show me pictures of X" posts that by now somebody would've compared the dark wheels.

 

My car is a Blu Mirabeau coupe. I don't want to go all the way to black with the wheels but I think a dark grey, not too glossy, would look really good. I've also found a few pics of blue cars with dark gold/bronze wheels although they've been on darker blue cars, Mirabeau is fairly light so I don't think I could pull those off.
