How to Use
Choose a Harmony Mode
Select from 6 color harmony modes: Random, Analogous, Complementary, Triadic, Split-Complementary, or Monochromatic. Each mode uses color theory to generate palettes that are mathematically harmonious and visually balanced. Set a base color to build your palette around a specific brand hue.
Lock, Refine & Resize
Lock your favorite colors and regenerate only the unlocked ones. Add or remove colors (2-10) to build palettes of any size. Click the edit icon to manually enter a specific HEX code. This iterative workflow mimics how professional designers build production-ready color systems.
Export & Share
Export your palette in 5 formats: CSS variables, Tailwind config, SCSS variables, JSON, or PNG image. Click any color to copy its HEX value instantly. Share your palette via URL so teammates can open the exact same colors in their browser.
Why Choose This Tool
6 Color Harmony Modes
Generate palettes using professional color theory: Complementary, Analogous, Triadic, Split-Complementary, Monochromatic, or fully Random. Each mode calculates hue relationships on the color wheel to produce combinations that are scientifically proven to work well together.
Flexible Palette Size (2-10)
Build palettes from 2 to 10 colors to match any project scope. Minimal 2-color schemes for clean interfaces, 5-color standards for brand systems, or extended 10-color scales for comprehensive design tokens and UI component libraries.
Shades & Tints Generator
Expand each palette color into a 9-step shade scale from dark to light: similar to Tailwind's color system. Click any shade to copy its HEX code. Perfect for building full design token sets with consistent lightness steps across your entire palette.
5 Export Formats
Export as CSS custom properties, Tailwind CSS config, SCSS variables, JSON data, or a downloadable PNG swatch image. Each format is ready to paste directly into your codebase or share with your design team: no manual conversion needed.
HEX, RGB & HSL Values
See HEX, RGB, and HSL color values for every color in your palette, plus the closest CSS color name. One-click copy makes it easy to use your colors in any design tool, stylesheet, or development framework.
URL Sharing & WCAG Contrast
Share any palette via URL: teammates open the link and see the exact same colors. Built-in WCAG contrast indicators show which colors pass accessibility standards for white text, helping you build inclusive, accessible designs.
