2 Good color tips: "Paint your walls in a manner that talks about the space you're in: Don't just paint one wall 'orange' and another 'red'; wrap the space in a single color to emphasize the space. This will give your spaces plasticity and make them seem continuous rather than 'choppy'."
"Limit your palette: Keep the colors you use on the walls to 3 colors; this will help tie the entire space together. You can always add other colors with your accessories for a little 'pop'."
