User reviews

Very useful. Intuitive interface.

It wrongly reports issues with labels with contrast as 4.56:1 for large text, where the acceptance criteria is 3:1 Also, AAA requires a contrast of 7:1. The underlying methods for recommending colors fails for pairs as #2111dd/#2ddddd - as a result, this extension suggests colors only for contrast 4.5:1 (AA or AAA-Large text)
