An Office 2007 theme is a new, standalone file type (.thmx) that defines colors, fonts, and effects to create a distinctive, visually cohesive look for all Office 2007 documents. Default themes include Office, Urban, and Opulent. You can find them in the themes gallery in each application: on the Design tab in Microsoft Office PowerPoint 2007 and on the Page Layout tab in Microsoft Office Word 2007, Microsoft Office Outlook 2007 email messages, and Excel 2007. Every Office 2007 document has a theme associated with it. Themes are available across Excel 2007, Word 2007, PowerPoint 2007, and Outlook 2007. Therefore, your communications or design personnel should spend some time, right away, creating themes that reflect your corporate identity.
