I loved my copper canyon granite so much, I had to run a 4" backsplash as I wanted to see it in front of me when I walked in the room! I found copper rust corinth slate tile that matches the floor and looks great from the granite up to the cabinets. I guess I am stuck in the 70's! haha. Plus, I just went from having a tile countertop and hated cleaning the white grout lines at the corners where the backsplash and the counters came together and vowed that I will never have a light color grout line to clean again. I guess it is all personal preference. I am not worried that the 4" backsplash will have any bearing on my resale value as I have a brand new kitchen in process and done by my DH with everything I ever wanted. Designed by me and installed with love! (mostly, but there is some grumbling at times) lol. And also, not planning to sell my home anytime soon.
