I think the simpler cream tile would be a good pick.

MrMastert, I think it could work. What you should do is get samples of the glass tile. Bring them home and put them next to your granite. It is important that the colors look right together. You cannot make this decision by looking at pictures.

Here is her kitchen.

use the same stone as the benches. that will look incredible. otherwise you are just changing one set of tiles for another. A bit like buying the same item of clothing over and over again in different colours. I do that all the time!?!

I would use a mid-range gray stone tile (like this: http://tilebar.com/3d-interlace-athens-gray-marble-tile.html) for your field tile. You have a great space above your range to frame out a "focal mosaic" if you would like. I would be glad to discuss how to commission that sort of custom design. PM me if you are interested. I have attached photographs to show you how cool custom mosaic focals look in my client's kitchens.
