StyleVars > Links > link_color

However since you have a dark style... you might want the links that grey color or another and simply forum titles another color so I would edit forumbits.css and find:

.forumbit_post .foruminfo .forumdata .forumtitle a, .forumbit_nopost .forumbit_nopost .forumrow .forumtitle a {
	font-weight:bold;
}

Now add in the color you want i.e.

.forumbit_post .foruminfo .forumdata .forumtitle a, .forumbit_nopost .forumbit_nopost .forumrow .forumtitle a {
        color: #ff0000;
	font-weight:bold;
}

You could also do a :hover version of that as well if you wish otherwise it will hover the same color .
