Colour Accessibility Websites and Tools

There are tons of other free and paid tools out there for checking accessibility. Here are a few I've used.

• Colorable (opens new window): A great way to visualize colour contrast issues for free.
• Eightshapes (opens new window): A quick way to generate a table of contrast ratios. Makes it easy to compare all your colours at once.
• Wai-aria tool (opens new window): The original contrast checker. Still works.
• Funky (opens new window): A freemium Chrome extension for testing a bunch of common accessibility issues. The free version is pretty awesome.
• Xscope (opens new window): A paid app for making sure your projects is lining up. Also has some good tools for checking vision accessibility issues.
• Sketch WCAG plugin (opens new window): An extension for Sketch. Select a bunch of colours, trigger the plugin, and get a nicely formatted webpage showing how colours rate against each other.
