Ok :visited works from the browser history, and I think you want to change the color of the clicked link only. I put some jQuery together

$('a').click(function(){
 if ( $(this).is(":visited"))
     $(this).removeClass("visited");
 else
     $(this).addClass("visited");
 });

and the CSS

    a{
color:#000;
text-decoration:none;
}

a.visited{
color:#205081;
}
