Interior paint should contribute a mood to a room. Using a color wheel can help select tones that are appropriate for different rooms in the home. Red and orange are warm colors, likely too bright for a restful lounging room which might be best in blues, which can be professional or airy. The color wheel can also supply suggestions for paint pairings. Opposing colors on the wheel are complimentary and bring out the best in each other. Warm tones are on one side and cool on the others. Use a simple color wheel next time you’re planning room design.
