7. Span the Spectrum
In feng shui, a rainbow of color is thought to bring harmony into a space; it's best applied to areas of your home where you frequently get tired, bored or feel the energy sink. Color psychology has also identified specific ways that viewing each color can affect us; a rainbow-colored rug, flower bouquet or even a cup of Sharpies on your desk can bring in a full spectrum of light waves that have great energetic as well as visual impact.
