Black. I have this in my own kitchen. The designer told me I'd never tire of the black granite (and I haven't 11 years), also the black granite if the highly polished type reflects everything from the back yard like a mirror, on the backsplash. If the granite is going up backsplash to the cabinets. Have black outlets installed and stainless switch plates, then, gray or white etc dab some Testor's paint on the outlets (whatever your granite is mottled with) and it'll look like the outlets are granite, too.
