Easy way to change background

[EMP]

From looking at the vB control panel the styles seem to be fully customizable. This is very powerful, but also very complex. If I simply want to have a different background image for each forum (perhaps different background colour, as well) - is there an easy way to do this?

Edit: I think I found it - the CSS page. Just a bit overwhelmed by all the options.

Yeah. vBulletin can be overwhelming at first, but it's actually quite easy to use, once you figure out what everything does.
