 Dear Makoto Ueki ,

The Web Content Accessibility Guidelines Working Group has reviewed the
comments you sent [1] on the Last Call Working Draft [2] of the

Working Group Resolution (LC-2893):
Thank you for your comment. The opinion of the working group is that the
color-contrast ratio of the link text when focused or hovered does not need
to meet 1.4.3/1.4.6. The goal of the color contrast success criteria is to
ensure that content can be read by users, so as long as the links are
sufficient contrast when not focused/hovered then they will meet
1.4.3/1.4.6.  

It is definitely preferred that focused/hovered link text also meet the
contrast ratios as this enables users to re-read and verify the target of
the link, but this represents more of a usability issue as the user can
easily read the link text by removing focus or moving their pointer off the
link.
