OKLCH Picker
Open SourceIntuitive OKLCH color picker for modern web designers
AI Summary
OKLCH Picker is a web-based tool for interactive selection and management of colors in the OKLCH color space. It enables designers and developers to create perceptually uniform colors while precisely controlling lightness and saturation. The tool is ideal for modern web projects that rely on accessible and consistent color palettes.
✓ Pros
- + Free and open-source with no hidden limitations
- + Intuitive operation with live preview of color changes
- + OKLCH space offers better perceptual uniformity than HSL/RGB
✗ Cons
- − Limited features for advanced color harmony calculations
- − At least basic knowledge of the OKLCH color model required
Use Cases
- → Creating accessible color palettes with uniform perceptual lightness
- → Designing responsive color systems for design systems and component libraries
- → Rapid prototyping of UI colors with visual preview
- → Exporting color tokens for CSS-in-JS and design token management
Who is it for?
Ideal for frontend developers, UI/UX designers, and design system curators who want to create modern, accessible color palettes with precise control.

What is OKLCH Picker?
OKLCH Picker is a web-based color tool that makes the OKLCH color space interactively accessible. Unlike HSL or RGB, OKLCH works with perceptual uniformity: two colors with identical L values appear equally bright to the human eye, which is regularly not the case with HSL. The tool runs directly in the browser, is free and open-source.
Core features
- Interactive OKLCH picker with live preview: changes to lightness, chroma and hue are visible immediately.
- Precise control over lightness and chroma, which simplifies building consistent color scales considerably.
- Export options for CSS-in-JS and design token workflows, so generated values can flow directly into existing token structures.
- Visual preview for quick UI prototyping without a separate design tool.
- No account required, no hidden restrictions in the free tier, because there is no paid tier.
Who is OKLCH Picker for?
The tool is aimed at frontend developers and UI/UX designers building color palettes for design systems or component libraries. Those already working with CSS Custom Properties and design token structures benefit most from the export workflow.
Anyone unfamiliar with OKLCH will first need to get comfortable with the coordinate system. L (Lightness), C (Chroma) and H (Hue) behave differently from their HSL counterparts. Without this basic understanding, it is unclear why certain color ranges cannot be produced, specifically when the chosen chroma value falls outside the sRGB gamut.
Dedicated functions for advanced color harmony calculations, such as automatically generated complementary or analogous color sets, are absent.
Context & alternatives
OKLCH Picker belongs to the category of specialized CSS color tools that go beyond simple hex pickers. Tools like Coolors or Palettte follow comparable approaches, though they are built primarily on HSL or RGB. For anyone building color systems according to perceptual criteria and targeting CSS-native OKLCH syntax, this is a focused tool that covers exactly that scope and promises nothing beyond it.
