Excerpt/Capsule: Learn about Office Themes and how they work specifically in versions of Microsoft Office on both Windows and Mac.
The whole idea of Office Themes (since Office 2007) is to provide a coordinated look in Word documents, Excel spreadsheets, and PowerPoint slides. Beyond that, the Themes also influence objects such as tables and charts in these applications. Newer versions of Microsoft Office extend the concept of Office Themes to other Office applications including Outlook, Access, Publisher, Visio, OneNote, etc. In addition, Themes are also supported in both Office 2008 and 2011 for Mac.
Figures 1, 2, and 3 show the Flow Theme that comes as part of Microsoft Office applied to a sample Word document, Excel sheet, and a PowerPoint slide.

You'll observe that there's so much coordination and unity of look in all three samples you saw.
That's not because the creators painstakingly made sure they used the same colors, effects, fonts, etc. but because all three were based on (or applied) the same Office Theme. It takes less than a minute to apply a new Theme, and change the look of a set of documents -- and as you will learn soon, it's so easy -- almost as easy as batting your eyelid four times in succession!
So how do you bat your eyelid, er.... apply an Office Theme to an existing document? That's something I'll explore next.
