This is where using Fire Fox with the FireBug plugin is a very helpful tool
Fire Bug allows you to select parts of your page top seer the CSS that is controlling it, and to also modify the css to experiment directly in the browser.
you will need to add new styles to the webassist/themes/tree/css/purple_styles.css file:
.links {
margin: 5px 0 0 5px;
}
.links a:link {
color: #000000;
}
