colorpicker.dev

An advanced, open-source color picker supporting multiple color models with wide gamut support and precision color handling.

All color models update in real-time as you adjust any slider, helping you understand how different color spaces relate to each other. Watch how adjusting HSL saturation affects HWB whiteness, or see how OKLCH's perceptual hue differs from HSL's mathematical hue. This live comparison makes it easy to understand when each color model works best.

• OKLCH - Wide gamut perceptual color space perfect for design systems. Access vibrant P3 display colors impossible in sRGB
• HWB - Intuitive whiteness and blackness mixing. Natural for adding white or black to pure hues
• HSL - Classic hue, saturation, and luminosity. Familiar and intuitive for quick color selection
• HSV - Hue, saturation, and value (brightness). Popular in graphics software, great for artists
• RGB - Direct red, green, blue channel control with alpha transparency
• HEX - Web standard supporting 3, 4, 6, and 8 character codes (with alpha support)

• Cross-format pasting - Paste any color format into any input field
• Auto-model detection - Automatically enables the appropriate color picker
• Precision preservation - OKLCH colors maintain full precision without sRGB conversion
• Gamut visualization - See P3 vs sRGB differences with dual color swatches

Built with modern web technologies:

• TypeScript & React - Type-safe, reactive UI
• Vite - Lightning-fast development and builds
• Zustand - Lightweight state management with persistence
• Culori - Advanced color math and wide gamut support
• CSS Variables - Dynamic theming and gradients

Unlike traditional color pickers limited to sRGB, this tool embraces OKLCH for accessing the full spectrum of modern displays. Pick electric blues and neon greens that were impossible with older color spaces.
