Harmonious colors sit beside each other on the color wheel. These colors work well together and create an image which is appealing, engaging and pleasing to the eye. Also referred to as analogous colors, a harmonious color scheme uses three to five colors that are beside each other on the color wheel.

While deft use of harmonious colors is vital in order to avoid visual clutter, noise and chaos on the picture plane, understanding color theory, primary, secondary and complementary colors as well as the color wheel is essential to establish harmony in color.
