What is Color Palette Generator?

Building harmonic color palettes requires balanced geometric relationships on the color wheel. Our Color Palette Generator calculates complementary, monochromatic, analogous, triadic, and tetradic schemes from any base color, featuring lockable swatch tracks, WCAG contrast accessibility indicators, and instant exports to CSS variables, Tailwind configurations, and JSON.

Designed for accuracy, speed, and privacy, this tool runs entirely on your local device with zero network latency.

How to Use the Color Palette Generator

  1. 1
    Select a color harmony mode: "Complementary", "Analogous", "Triadic", "Tetradic", or "Monochromatic".
  2. 2
    Pick a base color using the visual color picker or by typing an exact HEX code.
  3. 3
    Click the "Lock" icon on swatches you want to preserve while randomizing or adjusting neighboring tones.
  4. 4
    Copy individual HEX codes or click "Export" to copy CSS custom properties, Tailwind theme objects, or JSON.

Formula & Calculation Logic

Calculates geometric angular offsets on the 360-degree cylindrical HSL color wheel and derives lightness/saturation variations for monochromatic and tinted palettes.

Color Wheel Geometry: Complementary = (H + 180°) mod 360°; Triadic = (H ± 120°) mod 360°; Analogous = (H ± 30°) mod 360°
