how to change links at the bottom of drupal pages

I'm going to assume you know a little about CSS.

All links are under "#pager". If you want to change all the link colors, use "#pager a". There is also ".pager-current" that is the current page (it is not a link).

Add this to the style.css in the folder for the color you're using. Blue is in the base folder.

Here's an example.

#pager a {
    color: cyan;
}
