Harmony Modes

  • Complementary — two colors opposite each other on the color wheel.
  • Analogous — five colors adjacent on the wheel for a cohesive feel.
  • Triadic — three colors evenly spaced (120° apart) for vibrant contrast.
  • Tetradic — four colors in a rectangle pattern (90° apart).
  • Split-Complementary — a base color plus two colors adjacent to its complement.
  • Monochromatic — five shades of the same hue at different lightness levels.

Click "Export CSS Variables" to copy the palette as CSS custom properties ready to paste into your stylesheet.

Frequently Asked Questions

What is color harmony?

Color harmony refers to color combinations that are aesthetically pleasing. Harmonious palettes use mathematical relationships on the color wheel — like complementary (opposite) or triadic (evenly spaced) — to create balanced, visually appealing schemes.

How many colors does each mode generate?

Complementary generates 2 colors, triadic and split-complementary generate 3, tetradic generates 4, and analogous and monochromatic generate 5 colors each.

Can I export the palette?

Yes. Click "Export CSS Variables" to copy the palette as CSS custom properties (:root variables). You can paste them directly into your stylesheet.

What color format is used?

All colors are displayed and copied in 6-digit HEX format (e.g. #2563eb). You can convert them to RGB or HSL using our Color Converter tool.

Is my data sent to a server?

No. All palette generation happens locally in your browser. Nothing is uploaded.
