if you have chrome window trim, a stainless lip with matte black or gloss black center rim would be cool.
Alternatively the very clean look of silver csl rep style is always going to be safe on TiAg and good too.
I don't like all black rims - they often look cheap or take away from the wheels themselves. Never understood why pay 4000 for BBS rims and than powdercoat them matte black.
