Thanks for your reply,
So your saying the only way to do it would be in this list, actually..
<li style="color:#ccc;"></li>, <li style="color:#666;"></li>
?
would something work like this.. <li class="<?php (tag_ID) ?>">, <li class="tag_ID">
and it would give each list item its own class?
I hope I am being clear on what I am trying to achieve.
