UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Font size and color change.

I can only assume you are talking about the hyper links?
So when you expand a property in the style editor there will be a Special Link Properties that will appear when you expand that you will have the options to change the colors for:
Unvisited Link
Visited Link
Active Link
Hover Link

By the way you will need to do it for each property you want to change.
