Mastering Web Accessibility with Color Contrast

In the digital age, inclusivity is a necessity. Web accessibility ensures that digital content is usable by everyone. Our Free Color Contrast Checker is designed to help designers and developers create visually distinct and readable interfaces that adhere to the Web Content Accessibility Guidelines (WCAG) with high quality precision.

Why Color Contrast Matters

Poor color contrast is the most common accessibility failure on the web. By ensuring a proper contrast ratio using our free tool, you not only comply with legal standards like the ADA but also significantly improve the user experience for everyone.

Understanding WCAG Levels

The WCAG 2.1 guidelines define three levels of conformance regarding contrast:

  • Level AA (Minimum): Requires a contrast ratio of at least 4.5:1 for normal text.
  • Level AAA (Enhanced): Requires a higher contrast ratio of 7:1 for normal text.
  • 100% Free & Secure: Check as many colors as you want, privately in your browser.

Tips for Better Contrast
