Polypane Contrast Checker

Overview

Polypane's free checker computes contrast against both WCAG 2 and the newer APCA algorithm, and it accounts for opacity to report the real ratio over a background. When a pair fails it suggests the nearest passing color by nudging luminance. It is a precise, browser-based tool for designers who need accurate numbers and quick fixes.

Why we like it

  • WCAG and APCA in one place
  • Opacity factored into real ratios
  • Suggests nearest passing colors
