Thanks for your efforts. Long overdue. *MUCH* appreciated.
I did a quick test with Firebug to disable your a:link and a:hover CSS
rules. It looked fine to me in the "safety of blue".
Link styles (color and decoration) are a de-facto standard. DO NOT
CHANGE THEM. Invest CCS creativity elsewhere.
This is not just my opinion, it's my amplified interpretation of Jacob
Nielson, a usability expert with much more design experience than me.
I consider his guidelines to be on par with Damian's PBP's: great
sources of wisdom, distilled into rules, backed by well-considered
logic and augmented with discussion that allow me to break the
guideline in the (very rare) case that an exceptional condition (not
just a personal preference) really does exist.
Here's a personal story related to color:
As a child, our car got hit broadside by someone who "ran a stop
sign". As scared as I was, and as angry as I may have been with him,
I don't think he was at fault. I think the "stop sign" and the
transportation department were at fault. They choose a different
color (yes, blue), a different size (smaller and 2-3 feet shorter),
and a different location (center median instead of right shoulder) for
the "stop sign". He got a ticket for running that stop sign, but I
don't think it really was a stop sign. A stop sign that doesn't look
like a stop sign is *not* a stop sign. I think the transportation
department was recklessly endangering the public safety by (yes, get
this) bowing to public pressure to maintain a "common aesthetic" for
all signage within the planned community. They valued artistic
preference over well-known working functionality. Boo!!!
Here's a link to a reputable source. Jacob Nielson says it better
than I do. And he's invested millions of (other people's) dollars
studying real world people. He's not an academic tower theoreticist;
he watches real people then reports on what he observes.
Guidelines for Visualizing Links (http://www.useit.com/alertbox/20040510.html
Textual links should be colored and underlined to achieve the
best perceived affordance of clickability, though there are a few
exceptions to these guidelines.
I've only heard one compelling reason to change link colors. No, it's
not to match a "corporate color scheme"; folks spend 99.9% of their
time on *other* sites, so it's incumbent for usability that you
leverage that off-your-site learning. The only compelling reason I've
heard is to accommodate red colorblind folks; purple and blue are too
similar for them, and they can't distinguish visited versus non-
visited links. Search for US Government references to "Section 508" (www.section508.gov
) for further information. Here's another Jacob Nielson link
Change the Color of Visited Links (http://www.useit.com/alertbox/20040503.html
People get lost and move in circles when websites use the same
link color for visited and new destinations. To reduce navigational
confusion, select different colors for the two types of links.
It's unfortunate that "Perl blue" is so close to "link blue", but I
don't think that's a reason to change link colors. If you minimize
the "Perl blue" sections, I think the intent should be clear.
Thanks again for your efforts.
