We have a contemporary space with an open floor plan. The walls are continuous and it's making choosing a color difficult. We do however have a lot of natural light. I'm afraid to go too dark, but the white walls have to go. We have red dirt outside and the dogs have tinted the walls red in several areas. To make it worse, the previous owners painted in a matte finish so cleaning is impossible. I don't think red is an option. If you have any suggestions we'd really appreciate it.
