Color Scheme Generator

The color scheme generator produces complementary, analogous, triadic, split-complementary, and tetradic color schemes from any starting HEX value. Select a scheme type, enter your base color, and the tool calculates the correct color theory relationships and displays all resulting colors with HEX values and live swatches. CSS export is included for immediate use in your project.

Complementary and split-complementary color schemes

A complementary color generator pairs your base color with the hue directly opposite it on the color wheel, for example, blue with orange, or red with green. Complementary schemes produce the highest contrast and visual tension of any scheme type, making them effective for call-to-action elements, alerts, and highlights that need to stand out clearly against a primary color background.

Split-complementary schemes use your base color with the two colors adjacent to its direct complement. For example, if your base is blue, the split-complementary colors are yellow-orange and red-orange rather than pure orange. This approach offers similar contrast benefits to a complementary scheme but is easier to balance in a full design because the two accent colors are less extreme than a single direct complement.

Analogous and triadic color harmony

An analogous color generator selects three or four colors that sit adjacent to each other on the color wheel, such as blue, blue-green, and green. Analogous schemes produce the most harmonious and low-tension results, making them well-suited to calm editorial layouts, photography portfolios, and interface designs where visual cohesion is more important than high contrast.

Triadic color scheme generator results use three colors equally spaced 120 degrees apart on the color wheel. Triadic schemes are more vibrant than analogous but more balanced than complementary. They work well for creative, expressive brands. When using a triadic palette, choose one color as dominant and use the other two as accents to avoid an overly busy composition.

Frequently asked questions

A complementary scheme pairs colors that sit directly opposite each other on the color wheel, for example, blue and orange, or red and green. These combinations produce maximum contrast and visual tension, making them effective for call-to-action elements and highlights that need to stand out against a primary background.

Analogous schemes use colors adjacent to each other on the color wheel, such as blue, blue-green, and green. They create harmonious, low-contrast palettes suited to calm, cohesive designs. Triadic schemes use three colors equally spaced 120 degrees apart, producing more vibrant palettes that work well when balanced with one dominant color and two accents.

Complementary schemes work well for high-contrast landing pages and e-commerce. Analogous schemes suit editorial and portfolio sites where visual calm matters most. Triadic schemes serve playful, expressive brands. Split-complementary schemes offer high contrast with more variety. Whichever scheme you choose, run each color pair through the contrast checker before finalizing.

A tetradic or square color scheme uses four colors equally spaced 90 degrees apart on the color wheel. It provides the most color variety of any scheme type. Because of this high variety, tetradic schemes work best when one color dominates and the other three serve as accents, tints, or semantic highlights.
