We are painting our kitchen walls BM Revere Pewter and the cabinets and trim BM White Dove. We're using a marble similar to carrara for the countertops and a white subway tile backsplash. I'd like to paint the center island (appx. 9'x6') a grey accent color but I cannot decide what color to go with. I'd like something that is warm like the other two colors but also picks up the gray from the marble. Any suggestions?
