American manufactured Renaissance Collection Dark Silver iridescent glass tiles coordinate with the black pearl granite countertop in the otherwise light-colored bathroom in a residence in the San Francisco Bay Area.  The Dark Silver glass tiles appear dark grey (gray) or sometimes black, with rainbow iridescent highlights, thereby creating a dramatic, bold look, and with much more visual interest than a plain black tile floor.

A matching Dark Silver glass tile band was added to the formerly all-white tiled bathtub / shower wall.
