Alternating Colored Rows in vBulletin 4

[Spyike]

If you are referring to the text that is displayed when hovering over a thread open the Forum Display Templates in Style Manager, then navigate to FORUMDISPLAY. Double click it and search for the following:

<vb:if condition="$foruminfo['description']"><p class="description">{vb:raw foruminfo.description}</p></vb:if>

Change "{vb:raw foruminfo.description}" to what you want the text to say (will be universal for all threads).

If you are referring to the colors.. that is simply a style issue.

I do not see anything different on the image above from default vBulletin other than the two things I listed above
