Overview of customizing and saving a theme
You can quickly and easily format an entire presentation to give it a professional and modern look by applying a theme. A theme is a set of formatting choices that include a set of theme colors, a set of theme fonts (including heading and body text fonts), and a set of theme effects (including lines and fill effects).
PowerPoint 2007 provides several predefined themes, but you can also create your own by customizing an existing theme and then saving it as a custom document theme.
You can share PowerPoint themes with Word 2007, Excel 2007, and other Office programs to give your Office documents a uniform look. However, unlike Word and Excel, PowerPoint includes background style customization options. For information about adding and customizing backgrounds for your PowerPoint presentations, see Format the background of slides.
Customize a theme
To customize a theme, you start by changing the colors, the fonts, or the line and fill effects that are used. If you want to apply these changes to new presentation slides, you can save them as a theme (.thmx).
Customize theme colors
Theme colors contain four text and background colors, six accent colors, and two hyperlink colors. The colors in the Theme Colors button represent the current text and background colors, and the set of colors next to the Theme Colors name after you click the Theme Colors button represent the accent and hyperlink colors for that theme. When you change any of these colors to create your own set of theme colors, the colors in the Theme Colors button and next to the Theme Colors name change accordingly.
On the Design tab, in the Themes group, click Colors.
Click Create New Theme Colors.
Under Theme colors, click the button next to the name of the theme color element that you want to change.
Under Theme Colors, click the color that you want to use. Repeat steps 3 and 4 for all of the theme color elements that you want to change.
Tip: Under Sample, you can see the effect of the changes that you make.
In the Name box, type an appropriate name for the new theme colors, and then click Save.
Tip: If you want to return all theme color elements to their original theme colors, click Reset before you click Save.
Customize theme fonts
Theme fonts contain a heading font and a body text font. When you click the Theme Fonts button , you see the name of the heading and body text fonts used for each theme font below the Theme Fonts name. You can change both of these fonts to create your own set of theme fonts.
On the Design tab, in the Themes group, click Theme Fonts.
Click Create New Theme Fonts.
In the Heading font and Body font boxes, select the fonts that you want to use.
Tip: Under Sample, you can see sample text in the font style that you select.
In the Name box, type an appropriate name for the new theme fonts, and then click Save.
Select a set of theme effects
Theme effects are sets of lines and fill effects. When you click the Theme Effects button , you see the lines and fill effects used for each set of theme effects in the graphic displayed with the Theme Effects name. Although you cannot create your own set of theme effects, you can choose the one that you want to use in your own document theme.
On the Design tab, in the Themes group, click Theme Effects.
Click the effect that you want to use.
Save a theme
You can save any changes that you make to the colors, fonts, or line and fill effects of a theme as a custom theme that you can apply to other documents or presentations.
On the Design tab, in the Themes group, click More .
Click Save Current Theme.
In the File Name box, type an appropriate name for the theme, and then click Save.
The custom theme is saved in the Document Themes folder as a .thmx file and is automatically added to the list of custom themes.
