Our Mission

At A11y Colors Check, we believe that the web should be accessible to everyone. Our mission is to provide designers and developers with a powerful, easy-to-use tool to ensure their color choices meet accessibility standards and create inclusive digital experiences.

Why We Created This Tool

As designers and developers, we constantly face the challenge of choosing colors that are not only beautiful but also accessible. Checking WCAG compliance manually is time-consuming, and most existing tools lack the advanced features needed for modern design workflows.

That's why we created A11y Colors Check: a comprehensive tool that goes beyond basic contrast checking. Generate accessible color palettes, preview your designs in real-time, and export production-ready CSS—all in one place.

How It Works

Simply select your background and foreground colors using our intuitive color pickers (supporting HEX, RGB, HSL, and OKLCH formats). The tool instantly calculates the contrast ratio and shows WCAG AA/AAA compliance for different text sizes.

Need a complete color scheme? Use our palette generator with four different algorithms (Complementary, Analogous, Split Complementary, and Tetradic) to create harmonious, accessible color palettes. Export everything as properly formatted CSS variables ready for your project.

Our Commitment to You

We're committed to keeping A11y Colors Check free, accessible, and continuously improved based on community feedback. We support multiple languages and respect your privacy—no sign-ups required, no data stored.
