Kitchen Paint Color Advice?

I am updating my kitchen and dining room. I am changing the doors to red gloss, the kitchen walls are milk white and the worktops are black. I have an extension which makes the dining room part. What colour should I paint the two walls opposite the kichen cupboards? At the moment everything's on order so I've got no photos of the finished rooms.The walls are about 4 meters from the cabinets.
