Since your countertop material is pretty busy, I'd go with a larger scale tile, a pale or matching grout, and simple layout design.

THanks. I may be on the right track. just need to decide between two colors of tile

-Bianco Antico countertop

-cabinets painted white dove

-backsplash either top(white) or second color(beige)

If cabinets are white I would go with a deep beige, otherwise the backsplash will just blend into the cabinets.

This is my kitchen I like the dark counter & backsplash in between the cream cabinets.
