didn't have time to read all the answers. I have no backsplash and have never regretted it...been over 6 yrs. It is painted with BM matte...which has ceramic in it. It is as beautiful now as it was when first painted. I love the fact that I can showcase other things ...art etc in my kitchen and no competition. Also if I ever want to change it is as quick as a paint brush...expense is minimal..paint only ! All in all I think it is serene as you point out . Here is one pick. Since I have a lot of high heat cooking in my kitchen..built in deep fat fryer as well as gas cook top I can definitely speak to the longevity of paint only. c ( more at this album )

If your choice were only between to 2 you originally posted, I'd choose the one on the right--the cream one. From the photos it looks like it works very well with your quartzite. The gray one is "off" just enough not to look pleasing. However, as many have noted, either one is more difficult to clean than a smooth surface. What sort of cook are you--very neat or more devil-may-care? If you are very neat and do not splash much when you cook, then you may get away with the split-faced marble, but if you are a more exuberant cook, you may find it a challenge to clean. The mother of pearl is very formal and quite busy, so it's going to compete with the counter tops as well. Personally, I would use a smooth crackle tile in a tan/beige tone to work with your quartzite. Simple is always good.

I'd leave it too... it actually looks nice and coordinates with the wood edge on your counter. Your kitchen looks nice, good job!

OH BOY. I'm sorry I know you must be unraveled, but realistically it looks more like the counters dont go with your kitchen as they are brown tones and everything else looks black white and gray. Why did you leave the granite backsplash up? that would help minimize it a bit I think.. We need to see the whole room.
