Current page indicator

Hi all,

below is the code for the header of my page which shows the available pages. Only problem is that it does not indicate which page is currently showing in the main area. All I need to do is have the current page text in this header change to a different color, nothing fancy. Can anyone help, I’m new to php…

Thanks

<div id="topright">
<ul>
  <?php wp_list_pages('depth=1&title_li=0&sort_column=menu_order'); ?>
  <li><a href="#searchform">search</a></li>
  <li><a href="#main">skip to content &darr;</a></li>
</ul>
</div>

</div> <!-- Closes header -->
