Two ways to do this.
Your going to need advanced text.
Click on the text box that you want advanced text so that it has a blue border. Next click on the Object button at the top of VSD design window. Now in the Object properties box that opens to the right tic the "Allow Advanced Text" box. Now you can work miracles with your text.

or place this code to the head of the page that you want to override link colors. Tweak the HEX codes to your needs.
<style type="text/css">
#container a:link {color: #FF0000;}
#container a:visited {color: #800080;}
#container a:hover {color: #008000;}
#container a:active {color: #FF0000;}
</style>
