UBB.Developers Forums UBB.threads 6 V6 Modifications CSS Styles and Themes Change colour alt category

Hi

I take it this is something to do with stylesheets?

Is it possible to have the main categories darktable a different colour alternating like the forums.

EG..

MAIN PAGE *****************

Category 1...Heading Black
Forum1 Grey
Forum2 Grey
Forum3 Grey
Forum4 Grey

Category 2...Heading Black
Forum1 Lt Blue
Forum2 Lt Blue
Forum3 Lt Blue
Forum4 Lt Blue

Category 3...Heading Black
Forum1 Grey
Forum2 Grey
Forum3 Grey
Forum4 Grey

ETC........................

If so does anyone know how..

Thanks
