Thanks for your quick answer!

I think I understand the trick... but I can't seem to make it work. So maybe I think I understand it, but don't. Gah. LOL
I added the {cat_id} where supposed, & then in my style.css I added the following:
.maincat3 a:link, .maincat3 a:active, .maincat3 a:visited {
cursor: help;
text-decoration: none;
color: #00c4c4;
}
.maincat3 a:hover {
background-color: #00c4c4;
text-decoration: none;
color: #FFFFFF;
}
(3 being the ID of one of my categories...)
I get the default browser links for all categories, including my category 3.
Also... that modification would only change the color of links for the category link, wouldn't it? Because what I'd want would be to change the color of all links on the page, according to the category it belongs to... wouldn't I need to make other changes for that, like perhaps functions.php or... something? Oh my, sorry to sound so confused.
