2. Colour alone
When colour is used to show information, is it supplemented with text, icons, or other visuals to communicate information?
For example, this graph relies on the user being able to see the colours to know which bar represents which sport, so it fails this check.

How to test:
- Look for any examples where colour alone is used to communicate information.
- Check if there are any other means used to communicate the same information e.g. text, icons, shapes etc.
