Your kitchen is really quite lovely with its dark cabinets and countertops. I suspect that with better lighting you could have a wonderfully sophisticated look. However, if you want a change, I'd go with Caesarstone Frosty Carrina which resembles Carrara a bit.

For your backsplash, with what you have now, I would select a light taupe glass subway tile.

I agree, glass subway tiles would lighten things up. Perhaps a larger size ( 12x12).

Agree with Carolyn---but if you do decide to keep the counter-remove the 4" return before installing a backsplash... Beautiful kitchen---the wall color and floor is lovely... Good Luck!
