Re: Hyperlinks displaying as blue text only

As a low vision person like myself, I like the idea of having a different
color background when a mouse or keying over the link. This way it helps me
ensure that I'm in the right place to click on to the next page. It is
quite difficult for me to see the underline disappear when reaching the
link.

To specifically quote WCAG 1.0 checkpoint 2.1...

"Ensure that all information conveyed with color is also available
without color, for example from context or markup."

Links are, by their very nature, established by markup. So, any HTML
link is already marked up as a link. The information that a link is
present is conveyed by markup, not just the presence of blue (or blue
underlined) text.

So, even if the links were the exact same color, font, weight, etc., as
the surrounding non-link text on the page, they would still be links by
virtue of the markup.

Think of it a little bit in the reverse... the difference in color is
applied to give sighted people (who cannot immediately discern from a
visual interface) whether text is marked up to be a link or not unless
there is some visual difference to indicate such. The browser has no
such incapacity and can easily tell links from non-links even if they
are all 12-point black arial with no underlining. Tabbing through links
and other such browser-based activities function as expected.

To my way of thinking, there is no violation of the checkpoint here.
Whether that translates into greater ease-of-use is, as always, a far
different discussion.
