The addition of the color yellow in a bedroom or living room can really brighten things up. Even though technically white reflects more light, we associate yellow with the sun and with flowers, and so it seems even brighter than white. A simple way to add this touch of color is to use a yellow blanket on a bed or sofa. You may also want to consider drapes or throw rugs.
