Description
Scan any website and instantly find text with poor contrast.
Unlike basic checkers, this tool works on real-world sites with image backgrounds, gradients, transparencies, and all.
✅ Detects issues across the entire page in one scan
✅ Works with modern color formats (HEX, RGB, HSL, P3, OKLCH)
✅ Tests with both WCAG 2.2 and the newer APCA contrast standards
✅ Highlights where text passes, fails, or needs review
Perfect for designers, developers, and accessibility specialists who want future-proof contrast testing in a single click.
