Dove gray try Ben Moore.

Depends on how big the kitchen is. I would go with a light gray if the kitchen is small.

Blue green - you need a color to marry the two - something that looks great with both the white / pale gray and the gold wood. If the kitchen is small, a paler one - it will kind of echo the gray - bm wythe blue is a good color representation of the tone I envision. It really depends on your house' overall style. In a larger kitchen, even a navy / dark blue like bm van duesen could be stunning with white trim that crisply echoes the tops. Get your color story told in the kitchen - the walls are usually so small in relation to the other elements that wall paint can be like a terrific accent color . . .
