A free program for Chrome, by longmatthewh.
ColorA11y is a free tool for developers, designers, and engineers who want to make sure their websites are accessible to all users, including those with vision problems. It's easy to use and helps you check for accessibility issues quickly.ColorA11y can be used with any site, but it's designed to be used with web pages that have a significant amount of text. It will not work with pages that are loaded in an iframe or a frame.
The developer tools in Chrome will open the ColorA11y tab. The first thing you need to do is select a foreground color and a background color. The next thing is to select the type of contrast (color or text).
