Color harmony is the theory of combining colors in a fashion that is harmonious to the eye. In other words, what colors work well together. It is the reason the Hulk wears purple pants. It is the reason the original X-Men had yellow and blue uniforms. It is the reason behind almost all color design decisions.




Color harmony is based on the concept of a color wheel. You can study up on the history of it here. Essentially, it is a wheel with all the colors formed in a circle. Primary colors are on three equally distanced points of the wheel. Typically these are Red, Blue and Yellow. In the field of painting, where the color wheel originated, these three primary colors were used to mix almost all other colors. In modern printing these are replaced with Magenta, Cyan and Yellow. Black is thrown in to create darker colors, thus C, M, Y, K.


Between the three primary colors on the wheel are their mixed colors—purple between red and blue, orange between red and yellow, green between yellow and blue. Theoretically, all colors feels somewhere on the wheel.

The wheel represents color in a circle. Closer to the middle of the circle, colors are less pure. At the outer edge of the circle, they are more pure and more saturated. In 3D representations of the color wheel, one might add darkness and lightness separate from saturation. The thing that is important to know in color harmony is that how dark or light or how saturated colors are does not affect their position on the wheel. Orange can range from a dark brown, to a bright orange to a pale skin tone. All of these are ORANGE when it comes to the color wheel.




After the color wheel itself, the next important thing to understand is the key color. The key color is the most important color of your design. It is the color you can’t change or the color of the element you want to draw attention to. If you are doing a painting of the Hulk, your key color is green as it is the color you can’t change. If you are doing a photograph of a person, then their skin tone is your key color. If you are doing product photography, then the color of your product is the key color.

When determining your color harmony, you need to first determine your key color. From there, you can look at the various types of harmony and see which one you like best or which best suits your design.






This is the most basic harmony. It is a point opposite to the key color on the wheel. This “opposite” color is referred to as the complementary color and thus the direct harmony can also be called the complementary harmony. Virtually all color harmonies (except Analogous) are a variation of the direct harmony. It is the reason the wheel exists as opposed to a different kind of chart.

The high contrast of complementary colors creates a vibrant look especially when used at full saturation but can be jarring if not managed properly. This is the most common color scheme and is easy to find in all sorts of designs. Hulk’s green color has purple as its complementary color—which is the reason he wears purple shorts. Red and green are the Christmas colors and also happen to be complementary colors to each other.  In photography, blue is considered the best color to put behind a person as it is the complementary color to skin tone.


Rather than the point opposite the key color on the wheel, the split complementary takes the two colors directly on either side of the complementary color. This allows for a nicer range of colors while still not deviating from the basic harmony between the key color and the complementary color.

This color scheme has the same strong visual contrast as the complementary color scheme, but has less tension.  The split complimentary color scheme is a safe choice for virtually any design as it is near impossible to mess up and always looks good.



Also called Triadics or Triads. This refers to the color two spaces to either side of the key color’s complement. Essentially, with the triadic harmony, you are using three equally distanced colors on the color wheel. As such, you’re stretching the basic idea of color harmony and thus this harmony is best used with only touches of color.


Too much of each color and your design appears to have too many colors and can be too vibrant.





Also referred to as related colors, these are the colors directly on the left and right of your key color. They usually match up quite well and create a serene and comfortable design. While this color harmony can be pleasing to the eye, it can also come across as monotone. If you are going for a design that’s primarily one color, this is a good choice.




Similar to the Triadic, except that there are four points, all equally distanced on the color wheel.
