Generate a harmonious color scheme from a single starting color. Good palettes are not random; they follow relationships on the color wheel, and this generator builds those for you automatically. Choose a base color and a harmony rule, complementary for high contrast, analogous for calm neighbouring hues, or triadic for a balanced three-color set, and the tool rotates the hue mathematically to produce colors that sit together well. Each result comes with its hex code and a click-to-copy swatch, so you can drop the whole scheme into a design in seconds. Try different base colors and rules to explore options quickly. It all runs in your browser, instantly and privately.
