Color Combinations

Monochromatic (Single Color)

A combination of light and dark values of a single color on the color wheel. It creates a strong atmosphere. It's easier to focus on details. The result is a clean and elegant design. Attention should be paid to the parts you want to highlight. The design can be balanced with neutral colors.

Analogous

It is created by selecting colors that are adjacent to each other on the color wheel. Calm, soft, easy on the eyes designs can be achieved. Contrast should be considered to create emphasis. Emphasis is better achieved if one color is chosen as the dominant color and supported by others.

Complementary

It is created by using two opposite colors on the color wheel. Since opposite colors complement each other, they create a harmony that is pleasing to the eye, exciting and vibrant. One color should be more dominant than the other. Using both colors at the same time can benefit the eye and create confusion.

Triadic

It is the color harmony that occurs when we draw a triangle on the color wheel. These colors are equidistant from each other on the color wheel. A striking and dominant effect can be created. One color should be chosen dominant and the others balanced.

Split Complementary

Less contrasting than complementary colors. It is less applicable. There are two other colors besides the accent color. Softer designs can be created. Easy to apply.

Double Complementary

It is formed by the use of two pairs of contrasting colors. Dominant colors should be noted. One set of contrasting colors can be used for emphasis, while other contrasting colors can be used as complements.
