Paint Color Advice for Kitchen Walls?

We have a galley sized half bath off the kitchen and painted the walls a buttery yellow. We do not have much wall space in our kitchen because there is a dining room door, hallway door, basement door, back door, and bathroom door, and not much light. They will be painted all white including the trim around the doors. The flooring is a gray green tile look and the cabinets are off white. I thought bringing in the same yellow would brighten up the kitchen and the countertop would blend in.
