If red is your favorite color, you can use it in the bedroom, but use caution. Red stimulates, and too much of it can be overwhelming. Choose a muted tint, or try using red on just one wall, either behind your headboard or on a wall that has large windows, to break up the intense color. Be careful about using bare wood furniture in a room with pure red walls, as the two can clash. Better to go with painted pieces.
The tips for red also hold true for yellow. Softer shades will be more relaxing, and you don't want to go with too bright a shade in the bedroom.
Cool and soothing blues are a natural for the bedroom. In traditional bedrooms, deeper shades of blue create a stately backdrop for antiques and classic furnishings, as well as artwork. There are plenty of muted and pale tones of blue that create a soft look for those who don't want a dark color on their walls.
