Is it possible to change the font color and font type in the following script :

<script language="javascript">
(function(){ var centovacast = (window.centovacast||(window.centovacast={}));
(centovacast.recenttracks||(centovacast.recenttracks={})).config = {

    poll_limit: 60,        // specify how many times to poll the server
    poll_frequency: 60000, // specify the poll frequency in milliseconds
    track_limit: 0,        // maximum number of tracks to display (0=all)
    show_covers: 0,        // 1 to show covers, 0 to hide
    scale_covers: 1,       // 1 to scale covers to the default size, 0 to allow
                           // the web page to apply width/height via CSS
    buy_target: '_blank'   // target frame for "buy now" links
   
   

};})();
</script>

No, the above just controls the behavior of the JavaScript code.  Presentation is handled in CSS, so that's where you'd change things like colors.
