i'm not familiar with dreamweaver, i just use notepad. you can try and paste this in your head:
<style type="text/css">
a, a:visited, a:active, {
color:#000000; }
a:hover {
color:#ffcc00; }
</style>
if there is already a <style> section, just add the code to it. it should work for the whole page. this will make all of your links black, until they are "mouse-overed", in which case they will turn yellow. in-line style declarations will override this, as well as more specific declarations in the style sheet, such as:
td a:hover {
color:#ffffff; }
this would make all of the links, when they are "mouse-overed" turn white; but only if they are an elemt of the td, because it is more specific.

edit:
scratch all of that. i was wondering what you were talking about with the fading, cause it didn't look like fading to me. the "fading" doesn't work in mozilla, so scratch all of that above crap. it IS in fact done with javascript. I not real good with .js but you can usually finde pre-writtin scripts on the internet that do what you want them to do... anyway, if you look in the source code for this page you'll see a line that says something like <script ... blah blah.js> </script>
(there's probably a few of them) the particular script is not written in the soucre, it's a link to an outside script file... so on, so fourth...
anyway, you can find a similar code to do what you want here:
