change colour of level 1

[texasfan]

Hi, I installed this great programme a few days ago and I am using the Hardwired theme.
I created a few main gategories (level 1) with several subcategories. Now I like the lay-out when there are 2 levels displayed, but I find it pretty hard to distinguish the level 1 titles from the level 2 titles at first sight. That's why I would like the level 1 titles to be in a different colour, let's say soft yellow instead of white.
Can you please tell me how to do that? I can't really find in which file I need to do that.

Thanks a lot, Dirk

Can you post a link?

ah yes, sorry. The gallery is at http://www.texasindemand.com/photogallery
With the level 1 I mean for instance where it says : "Official and press photos (non live)" or "Concert photos and photos from TV appearances"

Thanks, Dirk
