  • You can use the WAVE browser plug-in to check your site, or you can go to the WAVE website and put in the url of your page to have it checked.
  • The WAVE tool tells you what errors it finds and provides links to additional information on the issues it finds.

Color Evaluation

WCAG Contrast Checker

  • WCAG Contrast Checker is a Firefox browser plug-in.
  • This plug-in checks the compliance of contrast levels of foreground and background color combinations based on the requirements of WCAG 2.1.

Color Contrast Analyzer

  • Color Contrast Analyzer is a Chrome browser plug-in.
  • This extension allows you to analyze text color contrast problems on a webpage according to the WCAG 2 text color contrast requirements. It evaluates the page as it appears in the browser, so it is able to handle text over gradients and advanced CSS attributes. You can choose to analyze a portion of a web page, the entire visible contents of a tab, or an entire web page.
