Generate beautiful color palettes from base colors
Generate beautiful color palettes from a base color using color harmony rules
Four schemes are built from your base color at once: Complementary pairs the base with the hue 180 degrees opposite it, plus blends of the two; Analogous uses neighboring hues for a calm look; Triadic spaces three hues evenly around the color wheel for vivid contrast; and Monochromatic keeps one hue while varying saturation and lightness. All math happens in HSL space so harmony stays consistent.
Use the slider to set 3 to 8 colors per palette, with 5 as the default. The "Include base color in palettes" checkbox, on by default, guarantees your original color appears as one of the swatches so palettes always anchor to your brand or artwork starting point.
Clicking any swatch copies that single hex code. A palette's Copy button places all its hex codes on your clipboard as a comma-separated list, ready to paste into design notes. Export downloads that scheme as a JSON file (for example, complementary-palette.json), and Export All Palettes bundles all four schemes into one color-palettes.json file.
All four schemes are derived live from the base color, so each edit to the picker, the hex field, or the random dice button immediately rebuilds complementary, analogous, triadic, and monochromatic sections. Use Regenerate All Palettes when you want fresh variations of the same base.
None. Every palette is computed by JavaScript on this page from your base color, and exports are created as local file downloads. Your color choices are never transmitted or recorded.
