Change color on template (CSS and photoshop etc.)

I just need the "Active" on the main menu changed into rusty red as on module header. In other words - i need "Forside||Velkommen" to look exactly like"Aktiviteter". (And off course this bg should appear behind other active links on the main menu. on [login to view URL] So... where the bright grey color show on main menu, i would like it to be rusty red like on the left module "Aktiviteter". I need this done right away - not in several days. Thanks for your interest. This can be easily done in less than an hour, if you know what you're doing ;) Let me know which files you need and ill upload them to change.
