Level AAA

At Level AAA, the requirement is taken further with an even more strict color contrast requirement for text. Essentially you can only use very dark colors on a very light background and vice versa. Almost all colored text fails.

Your average website doesn’t target Level AAA conformance, that level tends to be for pretty specialist sites as the criteria are really strict. That’s not to say that they aren’t helpful and it’s a good idea to at least understand them as there might be examples that are easy for your site to meet.¹

AAA Rules

Contrast

Contrast ratio between text and background is at least 7 to 1.
