We already discussed decorating with three colors with tertiary scheme, next is one style of decorating using only two colors. Complementary colors are the hues opposite of each other on the color wheel. Each color brings out the other and as you would say “complements” one another. Here are a few examples.
The next style that only uses two colors is called adjacent colors. These two colors are neighbors on the color wheel and harmonize each other. This room is a great example of how to work with adjacent colors.
