Light grey text on white might look stylish, but many people can't read it, especially on a phone in the sun. This checker tells you if your colours pass accessibility standards.

What you can do with it

  • Test text and background colour combinations
  • Check readability for normal and large text
  • Fix colours that are too faint

Good to know

Free and simple. Aim for at least the 'AA' standard for normal text.
