Maybe taupe or gray with a splash of color in pillows, blanket throw, curtains, etc. Check out some paint swatches to make sure what shade you'd like. You could do a wall as a focal wall, like a medium to dark blue with a taupe or gray. Sounds sleek and something that you'd enjoy on a long time basis. You could even have a little print. Hope you find what you need. Also check out hgtv.com. Roxanne
