[TYPO3] TT_news: Catmenu configuration

[Gunda]

Hi everybody,
We are using the "Latest" setting on one page of our website and the catmenu on 
another. Whereas, we were able to change the look (mostly colours) of the "latest" 
module, we have come to the end of trying to change the look of the Catmenu. 
When you look at the source view of the catmenu, it makes references to div classes 
that do not exist on either of the css-style sheets. Where does the catmenu and list 
settings get their layout configuration from? Where can I make changes to the 
colours?
Many thanks for any help in advance!
