Color Contrast Checker

Color contrast is critical for web accessibility and readability. When text and background colors don't have sufficient contrast, users with low vision, color blindness, or dyslexia struggle to read your content. The WCAG 2.1 standard defines specific contrast ratio thresholds that ensure text remains legible across different viewing conditions. This tool checks whether your color combinations meet those accessibility guidelines, helping you create inclusive digital experiences.

Simply select or input your text color and background color, and the tool instantly calculates the contrast ratio and tells you which WCAG levels your combination passes. A ratio of 4.5:1 is the minimum for normal text at AA level, while 7:1 is required for AAA. The tool also shows you exactly where your colors fall against these standards, making it easy to adjust colors until they meet your accessibility requirements.

Designers, developers, and content creators use this tool to audit existing designs and prevent accessibility issues before launch. Whether you're building a website, designing a mobile app, or creating marketing materials, checking contrast ratios takes seconds and can significantly improve usability for millions of users with visual impairments.
