Kitchen Paint Color Advice?

We are remodeling our kitchen; we are doing charcoal concrete counter tops with a gray floor tile. Our cabinets are a honey maple color. Appliances are black and stainless steel. We get the morning sun that shines in. What color should I paint the walls or should I paint the cabinets and leave the walls white? I have upload a picture, as you can see, we are still in the moving and prepping stages to install floors and counters.
