The "template" - I'm assuming you mean style - has been the same pretty much the entire time I have been using it. Many people have done customized versions based off the original style - some of which have been downright awesome. There are other ones available that show off some of the features of XenForo
The color scheme is the same on them all. The color scheme is fairly neutral and not an "in your face" color schematic that would offend many also.
I'm pretty sure with the release of 2.0, the style will be revamped, but I don't think you will see anything like you do on gamers forums, or minecraft forums.
