Hey Guys,
So for our infographic thought this was a good source. Use it when creating online courses, tells you if the contrast is strong enough between your text colour and background so that your web page is accessible. Will check the colours we have chosen and let you know if they pass, in case we want to use colours instead of black for some of the text.
