What is color harmony?

Color harmony refers to color combinations that are visually pleasing because they follow consistent angular relationships on the color wheel. Common types include complementary (180°), analogous (±30°), triadic (120° apart), split-complementary, and tetradic (90° apart).

What is a complementary color?

A complementary color sits directly opposite on the color wheel (180° hue shift). Complementary pairs create strong contrast and are often used for call-to-action buttons against a background.

How is an analogous palette made?

Analogous colors are neighbors on the color wheel. This tool uses ±30° and ±60° hue offsets to produce a five-color analogous set that feels cohesive and natural.

What is the difference between triadic and tetradic?

Triadic uses three colors equally spaced at 120° intervals. Tetradic (also called square or double-complementary) uses four colors at 90° intervals, giving more variety but requiring more care to balance.

Does the tool work with any hex color?

Yes. Enter any valid 3- or 6-digit hex code (with or without the # prefix). You can also use the native color picker to choose visually.
