WCAG Color Contrast Checker — Is Your Design Accessible?

Accessibility matters. And the most common failure is color contrast. I built a tool that checks any text/background color combination against WCAG AA and AAA standards. What it checks Level Normal Text Large Text AA 4.5:1 3:1 AAA 7:1 4.5:1 Features Live preview with your actual colors Color pickers + hex input Swap button to reverse colors Contrast ratio with PASS/FAIL for all 4 levels Color-coded ratio display (green/yellow/red) Contrast Checker More accessibility tools: Color Blindness Simulator Color Picker Full toolkit: devtools-site-delta.vercel.app
