As far as I'm concerned, you can't go wrong with black & white (or circles, but that's another post). There's something so classic and perfect about the contrast that never goes out of style and it can easily be freshened up by adding in pops of color. I'm loving this tile backsplash that I found in the June issue of Living Etc. magazine.
They actually just painted some of the white mosaic tiles black to create this geometric design, but it would be pretty easy to install this pattern if you were starting from scratch. It would also look cool if you used subway tiles for this, plus there would be less grout. I'm not sure if I could live with this backsplash in my home, but I can definately appreciate it's uniqueness.
