Using the color wheel to create a color scheme in your home makes the decorating process go smoothly. Using triadic colors -- three colors equally distant from each other on the color wheel -- will make your room memorable.
Each color has the same intensity, which creates a balanced room. Tie a sofa or chair color together with a colored pattern from curtains or rugs. Add in a variety of solid colors from each triadic color to bring the bold colors in the room in line.
Don't be afraid to use neutrals to break up the intense color -- this gives the room good grounding. Triadic color schemes create rooms that are vibrant without being overwhelming.
