You have put the cart before the horse. The order things are usually done in is floors, cabinets, counters, backsplash and then paint. Look at Extra White for the cabinets. But it is more important to match the floors and counters than the wall paint as you could always change that if it clashes with the other colors. After the cabinets are painted bring home tile samples until you find the right backsplash. If you haven't used Samplize yet, look into them. You might want to try a couple whites. They sell peel and stick samples that you can move around the room.

agree with other^^^

i would paint the cabs a color in your granite. seems like a 'busy' granite and i would not want to add another color to the kitchen. i don't see any gray in that granite, so i would consider painting the walls? unless it is different IRL.

your floor sample and actual floor do not seem the same color. is the floor going to be changed?

you can add color with accessories - towels, rugs, art etc...
