Color Contrast Checker

Color Contrast Checker Overview

Check WCAG accessibility contrast

The Color Contrast Checker is an essential accessibility tool for web designers and developers. It checks the contrast ratio between your text (foreground) and background colors to ensure compliance with WCAG (Web Content Accessibility Guidelines) AA and AAA standards. Good contrast is vital for users with visual impairments and improves readability for everyone (e.g., in bright sunlight). The tool provides instant pass/fail feedback for "Normal Text" and "Large Text" sizes, helping you choose accessible color palettes for your digital products. You can input colors using Hex, RGB, or HSL values.
