OKLCH is a perceptually uniform space supported by CSS Color 4. Contrast follows WCAG 2.1 — body text should reach 4.5:1 (AA).

关于Color Converter

Color code conversion keeps the same color while rewriting notation—HEX, RGB, HSL, OKLCH—for design systems and CSS variables. toco.tools converts values and shows a live swatch entirely in the browser. Displays vary by monitor gamut; verify contrast for accessibility and print separately.

使用方法

  1. Enter a color value
  2. Review converted formats
  3. Copy the notation you need
