What is color harmony?
Color harmony is the theory of selecting colors that work well together visually. Designers have used these principles for centuries. The harmonies are based on the positions of colors on the color wheel: colors opposite each other (complementary) create vibrant contrast; colors next to each other (analogous) create serene, natural-looking combinations; three evenly spaced colors (triadic) create vibrant yet balanced palettes. Knowing which harmony to apply helps you build color systems that feel intentional rather than random.
The five harmonies explained
Complementary: Two colors directly opposite on the color wheel — maximum contrast, great for call-to-action elements. Analogous: Three to five colors sitting adjacent — harmonious and easy on the eye, common in nature. Triadic: Three colors evenly spaced 120° apart — vibrant and balanced, a favorite for illustration. Split-Complementary: A base color plus two colors adjacent to its complement — contrast without tension. Monochromatic: A single hue in five different lightness levels — elegant and cohesive.
How to use the generated palette
Click any swatch to copy its HEX code to your clipboard, then paste it into Figma, CSS, Tailwind config, or any design tool. Monochromatic palettes are ideal for typography hierarchies and background layers. Complementary palettes suit bold brand color pairs. Analogous palettes work well for gradient-heavy designs or illustrative UI. Triadic palettes are excellent for dashboards that need to distinguish between three data series.
Color theory basics for developers
The generator works in HSL color space — Hue (0–360°), Saturation (0–100%), and Lightness (0–100%). Harmony rules shift the hue by specific degrees while keeping saturation and lightness similar. The resulting colors feel related because they share the same saturation and lightness level, only differing in their position on the color wheel. Understanding HSL makes it much easier to reason about color relationships than working with HEX values directly.
