I had black tiles in my last house and used grey which looked great but if you have not yet bought the tiles, or can change them, do so beware, a nightmare to keep black tiles of any type, doesn't matter where you put them they pick up everything. I have them on my porch floor presently and hate them as they NEVER look clean, Actually plan on removing them as soon as I find something else easier to keep clean, like cream which never shows up the dirt, good luck anyway.
