ColorA11y

SUMMARY

ColorA11y allows you to easily select a foreground color and a background color, and determine whether or not the contrast ratio between the 2 colors is WCAG 2.0 compliant. ColorA11y can help validate the existence of web accessibility issues you think you already have with color contrast. This Developer Tools extension can also help verify you're technically adhering to the WCAG 2.0 color contrast guidelines. Simply open the Developer Tools in Chrome, and open the ColorA11y tab. Currently, this works best using Mac's color picker, and not the Windows native tool. I'm working on integrating this with Spectrum, and will have an update shortly.

The latest version of ColorA11y is available on the Chrome web and is currently being used by 1,000 active users. The initial version was launched on 2015-06-19.
