What color should I paint my walls to create a clean crisp modern look. I have a bathroom that has big rectangular black floor tiles placed in a subway pattern. In one corner of the room the shower wall also has the same black tiles behind the glass doors. On the other corner of the room there is a long rectangular tub with ths same black tiles wrapped around two of its sides. The walls are painted white. I have a dark brown cabinet with an above the counter sink (white).
