As you're probably aware by now, Office 2007 introduces Themes; professionally created collections of colors, effects, and fonts, which can be applied to Word, Excel and PowerPoint documents. Themes provide a uniform professional look across different document types, as well as providing powerful customization options.
- Apply your theme of choice from the Theme gallery of the Design ribbon; it will then appear in the gallery. If you downloaded any of the approved templates from http://www.unl.edu/ucomm/ucomm/resources.shtml, you will need to select Browse for Themes… in the gallery to navigate to and select the theme.
- With the gallery open, right-click the theme thumbnail you want to make the new default and select Set as Default Theme.
