The world is divided into two groups—the color courageous and the color cowardly. People who live in colorful interiors have gotten over the fear of making a mistake. The best way to get over that fear is to always start with a color you love—from a rug, a painting, a fabric. Then test it on the wall. If it's too strong, consider asking your paint store to formulate it at "half-strength" to lighten it or to tone it down by adding more gray.
