🎨Tailwind CSS & OKLCH Color Palette Generator Documentation & Guide

CSS & Design
The Tailwind CSS & OKLCH Color Palette Generator transforms any single HEX or CSS brand color into a perceptually uniform 11-step tint and shade scale (50 to 950) powered by the modern OKLCH color space. It automatically evaluates WCAG accessibility contrast ratios and generates copyable configurations for Tailwind CSS v3, Tailwind CSS v4, and native CSS custom properties.

📋How to Generate a Design System Palette

  1. Choose Seed Color: Type a 3- or 6-digit hex color code, select a preset theme chip, or pick a hue with the visual color picker.
  2. Configure Token Name: Name your color family token (e.g. brand, primary, neutral) to customize generated CSS variable names.
  3. Generate Palette: Click 🎨 Generate Color Palette to compute the 11-shade progression and evaluate WCAG contrast ratios.
  4. Export Configuration: Select your framework format (Tailwind v3 config, Tailwind v4 @theme, CSS variables, or Design Tokens JSON) and click 📋 Copy.

⚙️OKLCH Color Space & Contrast Mechanics

Unlike legacy sRGB and HSL color spaces which suffer from non-uniform perceived brightness, OKLCH models human visual perception accurately:

• Perceptual Uniformity: In HSL, pure yellow (hue 60°) has a perceived lightness of ~97% while pure blue (hue 240°) has ~30%. In OKLCH, lightness (L) is decoupled from chroma (C) and hue (h), ensuring constant visual brightness across hues.
• 11-Step Lightness Curve: Follows standardized ergonomic lightness anchors: 50 (0.97), 100 (0.93), 200 (0.86), 300 (0.76), 400 (0.65), 500 (0.55), 600 (0.45), 700 (0.36), 800 (0.28), 900 (0.20), and 950 (0.13).
• WCAG 2.2 Relative Luminance: Evaluates contrast ratio (L1 + 0.05) / (L2 + 0.05) against pure white and black to display instant AA (4.5:1) and AAA (7.0:1) accessibility badges.

💡Practical Use Cases & Design System Architecture

  • Tailwind CSS v4 Migration: Generate modern @theme CSS custom property blocks for new Tailwind v4 projects.
  • Design System Token Architecture: Build consistent 11-step UI palettes with guaranteed accessible button and text contrasts.
  • Brand Identity Scalability: Expand a single client logo color into a full functional suite of borders, hover states, and background tints.
100% Client-Side Privacy Guarantee:All color space transformations, matrix conversions, and configuration exports run 100% locally in your browser. No brand assets or colors are ever sent over a network.
