A Web page that is as conformant as possible would meet SC 1.4.6 and would have a 7:1 contrast ratio. However, at Level AA this is only advisory, and a 5:1 ratio would conform. Thanks again for the interest that you have taken in these guidelines. Could we ask you to let us know whether or not you are satisfied with this response by Wed, April 9?
