Color theory has real practical value for designers, explains Playing with Color author Richard Mehl. The principles of color theory are just like the other design principles we use every day—they are creative tools that can be used to solve visual problems.
In visual communication, a color palette is a set of colors that work together to express an idea—loud, quiet, light, heavy, warm, cool, conventional, avant-garde, etc. Most color palettes used in graphic design projects, like branding, are built around a base color, sometimes called a “hero color.” The hero color is usually supported by two or more colors. Some brands use two hero colors.
Choosing a hero color is often the easiest part of creating a color palette. The hero color is usually associated with a familiar idea. For example, we associate blue with cool temperatures, orange with warmth, red with passion, green with growth. A blue hero color can signify ideas related to coolness, like calm, serenity, peace. Nuance can be added to the expression by adjusting the lightness, temperature, or saturation of a hero color—all forms of color contrast.
The supporting colors work with the hero color to express or complement the idea. Choosing the supporting colors isn’t always as easy as choosing the hero color. A basic awareness of color theory is helpful, especially the theories of color contrast. Let’s say our hero color is red. If we want our color palette to express unity, we can make the supporting colors analogous to red. A palette of analogous colors will almost always express unity because there is minimal contrast. Another way to express unity is to use monochromatic colors—a set of colors, all based on the same hue, but varying in lightness and darkness.
Primary colors and their cousins, the secondary colors, are color systems defined by extreme contrast, and they make excellent color palettes. We can build a color palette around a primary color or secondary that expresses difference. For example, if red is our hero color, and we choose the other primary colors—yellow and blue—as supporting colors, the palette will express extreme contrast and really pop. The lightness of yellow, and the coolness and relative darkness of blue, make the sensation of these hues completely distinct from the sensation of red.
Extreme contrast can also be expressed with complementary colors. Red and green, blue and orange, yellow and violet are all opposites on the color wheel, and therefore, they represent the greatest difference in hue—the ultimate form of color contrast. As I write this, I’m watching the New York Mets playing in the World Series. Their brand colors are blue and orange, and as noted color theorist Johannes Itten wrote, they “…incite each other to maximum vividness.”
We see extreme contrast demonstrated in every set of complements. But at the same time, we commonly see complementary colors together in nature and other examples of local color. We associate complementary colors with each other, so even though they are opposites, they seem like natural companions in a palette.
I’m a big fan of this program. It has become an important part of my creative toolkit. It allows me to experiment with a variety of color theory principles to create color palettes. Try it for yourself and see what palettes you can come up with for your next design project.
