This is how I do it:
1. Look up how to make CSS type files and save it into your website directory.
2. Put the following lines in HTML View after the <head> tag
Change the color according to your own preference. The one below, highlights
the link in red.
the a:hover removes the underline (however, here it changes the color)
<style type="text/css">
a:link {text-decoration: none; color: #000000;}
a:active {text-decoration: none; color: #000000;}
a:visited {text-decoration: none; color: #000000;}
a:hover {text-decoration: none; color: #FF0000;}
</style>
