Active Text Colour

[Gersfan]

In the CSS there is Normal, Visited and Hover, what about Active?
How do I set the forum sections only on the Index to appear the same colour as my hover when there is new posts in that section (Active)

I know it works, i've done it before, it's a simple template edit but because I've got a new forum installed I can't remember how to do it.

Thanks,
