pages you're hosting, or pages you view? if you use a global CSS style, it'll change everything... I don't know if you CAN do specific links without editing the site's source code. Here's what it'd look like to change all url links to purple though:
Code:
a {
color: purple;
}
far as i know, you put that in a foo.css file and point your browser at it, and all a href="blah" links will be purple. you can also put the hex code for colors in there.
edit: here's a list of other stuff you can do with CSS.

the bit outside the curly braces determines what tag your modifying, and the stuff inside specifies values. you can also do
Code:
.foo{
attributes here
}
then in certain tags do sompething like
[a type="foo"] (with angles of course) and it'll apply only to those tags. there's a 3rd kind that are declared with a
#foo{} but I'm not clear on how they work.
Hope that'll get you started
