Alternatively you can try this as well. I just tested it and it works fine.
At the node_link_level_2 template find the following code:
Code:
<div class="nodeText">
<h3 class="nodeTitle"><a href="{xen:link link-forums, $link}" data-description-x="#nodeDescription-{$link.node_id}">{$link.title}</a></h3>
<xen:if is="{$link.description}"><blockquote class="nodeDescription muted baseHtml" id="nodeDescription-{$link.node_id}">{xen:raw $link.description}</blockquote></xen:if>
</div>
And change it to:
Code:
<div class="nodeText">
<h3 class="nodeTitle"><a href="{xen:link link-forums, $link}" data-description-x="#nodeDescription-{$link.node_id}"><span style="color:red;">{$link.title}</span></a></h3>
<xen:if is="{$link.description}"><blockquote class="nodeDescription muted baseHtml" id="nodeDescription-{$link.node_id}">{xen:raw $link.description}</blockquote></xen:if>
</div>
This will color the link titles forums in red. You can change the color to whatever color you want at this part:
Code:
<span style="color:red;">{$link.title}</span>
Here is a screenshot with the end result.
