Triadic color schemes are a fairly simple concept. They consist of three points on a color wheel that are evenly spaced away from each other, much like the points of an equilateral triangle. Because of the way the colors lay on the color wheel, they're often thought to be a fantastic example of contrast working well with harmony. A simple example of a this specific color scheme is red, blue, and yellow.
These are high-contrast while not being as urgent as complementary and split-complementary color schemes. It's able to get your attention without feeling too overpowering. Here's an example of how this scheme looks on a color wheel, as well as an example of a the scheme's palettes.
Discovering Your Target Audience
Because they tend to offer a fair amount of contrast from the other colors, triadic color schemes tend to feel a little juvenile, but you can easily use that to your advantage. Rather than targeting an adult audience, these palettes are perfect for toddlers, kids and tweens. At full saturation, these colors are playful and fun, exerting a feel of energy without urgency. Just like analogous color schemes, it's a good idea to pick a single color with two accents, or even better, use these colors to supplement a mostly white layout.
Want a fantastic, popular example? Look to the left! Crayola's website uses bright, primary colors to market its very familiar brand of children's art supplies. These colors are attractive to young children who seem to be drawn to the high energy of bold primary colors. Not only do children associate these bright colors with fun, parents tend to be drawn to things that are brightly colored when looking for services and products for their kids. So this is a great theme if you run a daycare website, are creating signage for a playground or designing graphics for children's clothing.
If you find that the color scheme still feels too bold for your liking, lower the saturation or the brightness of the colors involved. By doing this, you can easily expand the audience your palette can target.
