Different color scheme on Nav Bar buttons

[Doofendugel]

Is there a simple way to make a different color for a nav bar button that will ovrerride the admin panel settings of the basic vbulletin settings? If all the text line of the buttons are black, how do you make one button a different color? I am primarily thinking of search and FAQ buttons here, but can see a reason to highlight different buttons depending on the site and useage.
