empty cart sidebox background colour

Hi,
i am trying to change the background colour of the sideboxes, firstly I'm trying the empty cart sidebox.

Having searched through the css, i thought that this would work:

#cartboxempty {
background-color: #333399;
}

But it doesn't work. I think that the above css id may only apply to the text in an empty cart.

Any ideas guys/gals?

Managed a work around that achieves the same result, I just edited:

#navColumnOne, #navColumnTwo {
background-color: #333399;
}

So the above issue is resolved, however. I am now looking to change the colour of the categories, info links, etc. Basically all the links in the sideboxes. I have been ploughing through the css file making various changes to different id's such as:

sideboxcontent
category-products
etc

I then thought that it might be one of the basic id's at the top of the css, but after trying still cannot find a way of changing the text colour.

I am certain it is right in front of me

Thanks
Pete
