Color Palette Generator — Complementary, Triadic, Analogous Palettes Free Online

Build Beautiful Color Palettes in Seconds

Picking the right color palette is one of the hardest parts of design. Color Palette Generator takes your base color and generates six types of harmonious palettes — all client-side, no signup required.

What It Does

  • Complementary — opposite on the color wheel (180°)
  • Triadic — three evenly spaced colors (120° apart)
  • Analogous — neighbors on the wheel (±30°, ±60°)
  • Split-Complementary — base + colors adjacent to its complement
  • Square — four evenly spaced colors (90° apart)
  • Monochromatic — seven shades/tints of the base

For every swatch you get HEX, RGB, and HSL values with one-click copy. There's also a CSS variables export panel ready to paste into your stylesheet.

Try It

👉 color-palette-gen-bxd.pages.dev

Pick a color, hit Random, or type a hex value. Switch tabs to explore different harmony types. Click any swatch to copy its value.

Tech Stack

Pure Vanilla JS — no frameworks, no build step, no server. All color math (HSL ↔ RGB ↔ HEX conversion, hue shifting, lightness adjustment) runs in the browser. The tool is hosted on Cloudflare Pages so it loads fast from anywhere.
