Follow the 10-30-60 Rule
Once you have your color scheme decided, you’ll need to decide how they will work together. This is where the 10-30-60 rule comes into play. Choose a dominant color which you’ll use for 60 percent of the space, a secondary shade (30 percent) and an accent color (10 percent).
Dominant colors are often applied on walls and floor coverings. Secondary colors work well on furniture and the accent color is reserved for accessories such as throw pillows, a flower vase or a lamp shade.
