Being developed by Deque Systems (the same company behind products such as axe-core and Axe Dev Tools), this color palette contrast analyzer is a web service that allows you to quickly check the contrast ratio between all colors in your color palette. You can input up to 5 colors, indicating wether they are used as foreground, background or both, and the text font size. The service will generate al possible color combinations, showing for each of them:

  • a sample text, with the color combination applied;
  • the contrast ratio;
  • wether contrast is enough to pass WCAG level AA or AAA conformance validation.

The source code that implements this web service is available on Github.
