Color Harmony Generator for Balanced Color Palettes
Choose a base color and one of six harmony rules to generate a coordinated palette. The Color Harmony tool rotates around the hue wheel: complementary finds the opposite, analogous finds neighboring hues, triadic and tetradic space colors evenly, split-complementary selects neighbors of the opposite, and monochromatic stays within one hue. Click any swatch to copy its hex value.
The Color Harmony generator creates color palettes from a base color using familiar relationships on the hue wheel. Choose a harmony rule to see the related colors as swatches, then click a swatch to copy its hex value. It is a handy color palette generator when you want to explore combinations without assembling them by hand.
The available rules produce different relationships: complementary finds one opposite hue, analogous uses neighboring hues, and triadic and tetradic palettes space colors evenly around the wheel. Split-complementary uses the two neighbors of the base color’s opposite. Monochromatic palettes focus on one hue. Select the rule that suits the palette you want to explore, then compare the generated swatches.
Color Harmony is useful when you need to turn a starting color into a set of related options. A color palette can help you plan colors for an interface, prototype, or other project. The tool provides hex values you can copy, making it easier to carry a chosen swatch into your development or design workflow.
The tool runs entirely in your browser, so your input is processed on your own device and nothing is uploaded, stored, or sent to a server. It works offline once the page has loaded, and it is free to use. Developers, DevOps engineers, designers, and anyone exploring color combinations can use it without installing anything locally.
Step 1: Enter or paste a base color to start building a palette.
Step 2: Choose a harmony rule: complementary, analogous, triadic, tetradic, split-complementary, or monochromatic.
Step 3: Review the generated swatches to compare the colors in your palette.
Step 4: Click any swatch to copy its hex value for use in your project.
