Placid earth tones play into the mood of a bedroom. They’re appealing colors that reflect the world of nature in their warmth. Ranging in tones from the boldness of bittersweet chocolate brown to the lightness of pale marigold, an earth-toned palette opens the door to multiple accents. Paint the feature wall behind the headboard in a strong color -- British racing green or sienna -- and use diluted shades of the feature color for the remaining walls. Window, ceiling and floorboard trim that’s painted a crisp white sets off your color of choice. Accent with bedding using sage green, lilac or lavender, and a touch of either mellow yellow or rust.
