Our flooring. Sorry would not let me add into post.

I have similar granite and I'm going with Florida tile Bliss mosaic - it comes in different colors . Try to look at in in person rather than photos. It has a mixture of stone and glass which looks great with the granite.

I think you want to let the granite shine here (especially in combination with the nice flooring), so I'd go with a simple white subway tile, which should give a nice contrast with both cabinets and counter while not drawing too much attention

.

I used a simple stone backsplash with my granite and also have light cabinets. I did the kitchen 5 years ago and still happy with my choices.

My sister has your exact combination and used the type of tile below but all in beige. They really compliment each feature in the kitchen and feel modern, yet handmade and warm - which is what I think you have with your choice of granite and cabinet door.

What about a using the granite as the backsplash?
