Color Wheel Palette Generator

An interactive color palette generator built with React, TypeScript, and Tailwind CSS v4. Pick a base color on a color wheel, choose a harmony type, adjust tint/shade, and export palettes in multiple formats.

Features

  • Interactive Color Wheel — Canvas-based HSL wheel with drag-to-select hue and saturation. Touch support for mobile.
  • 7 Harmony Types — Complementary, Split-Complementary, Analogous, Triadic, Tetradic, Square, Monochromatic.
  • Tint & Shade Slider — Adjust lightness in real-time.
  • Color Input — Enter HEX values directly, view RGB/HSL, adjust via RGB sliders.
  • Click-to-Copy — Copy any color value (HEX, RGB, HSL) to clipboard.
  • Export — CSS variables, JSON, Tailwind config snippet, or PNG image.
  • Dark / Light Theme — Toggle between dark and light modes.
  • Responsive — Mobile-first layout with horizontal scroll palette on small screens.
