Does this exist?

Bit of background first.
I'm using vers. 4.1.7
On the main page all the categories are listed and the sub forums within the categories. I'm using the standard default style so all the subforums in the list have the white background and blue(ish) ttext.

Is there a mod, or something, that will allow me to change the background colour of the sub forums listing in just one category, so that it stands out from all the others on the main page.

I'd like to do this without changing the rest of the style of the forum.
