Modifying Themes in PowerPoint

Have you ever encountered a professional theme that perfectly captures the structural tone of your presentation, yet fails to align with your specific branding or preferred color palette? This is a common design challenge. Fortunately, PowerPoint’s architecture is remarkably flexible, allowing you to decouple a theme's style from its specific colors, fonts, and effects. By mastering the art of mixing and matching variants, you can engineer a unique visual identity for your project while maintaining the professional integrity of the original theme.

To select new theme colors:

If the structural layout of a theme meets your requirements but the color scheme feels inappropriate, you can swap the entire palette in seconds. This process preserves all other design attributes—such as slide layouts and background graphics—while refreshing the visual tone.

1. Navigate to the Design tab on the Ribbon.
2. Locate the Variants group, click the drop-down arrow, and hover over Colors.

3. Browse the available palettes. As you hover, the presentation will provide a real-time preview. Click to apply your selection.

To customize colors:

Standard palettes may not always suffice, especially when adhering to strict corporate branding. Did you know that you can exercise granular control over each individual color within a theme's set?

1. From the Design tab, open the Variants drop-down menu.
2. Select Colors, then click Customize Colors at the bottom of the list.

3. A dialog box will launch, displaying the 12 current theme colors. To modify a specific element (like an accent or hyperlink), click its drop-down arrow and choose a new shade.

4. Provide a unique identifier in the Name: field and click Save.

To select new theme fonts:

Typography is a vital component of a presentation’s "voice." Unifying your headings and body text through a set of theme fonts ensures a cohesive reading experience without altering the graphical theme elements.

1. On the Design tab, click the Variants drop-down arrow and select Fonts.

2. Choose from the curated pairings designed to work harmoniously across all slides.

3. The presentation will update to show the new theme fonts.

To customize theme fonts:

If your project requires specific typefaces, you can define your own theme font pair. This ensures that any new slides you add will automatically adopt your chosen typography.

1. From the Design tab, click the drop-down arrow in the Variants group.
2. Select Fonts, then click Customize Fonts.

3. A dialog box will appear with the two current theme fonts. To change the fonts, click the drop-down arrows and select the desired fonts.
4. In the Name: field, type the desired name for the theme fonts, then click Save.

5. The presentation will update to show the new custom theme fonts.

To select new theme effects:

Effects determine the visual styling of shapes, lines, and SmartArt—controlling attributes like shadows, reflections, and 3D bevels. Changing the theme effects is an efficient way to alter the "depth" and sophistication of your graphics across the entire deck.

1. From the Design tab, select Effects from the Variants menu.

2. Select the desired theme effects.

3. The presentation will update to show the new theme effects.

Background styles

The background serves as the canvas for your content. Depending on your current theme, you can choose from a range of coordinated Background Styles to further distinguish your slides from the standard presets.

To apply a background style:

1. From the Design tab, click the drop-down arrow in the Variants group.

2. Select Background Styles.

3. Select the desired style. The available styles will change depending on the current theme colors.

4. The new background will appear in each slide of your presentation.

If you want even more control over the background, click the Format Background command on the Design tab.

Saving custom themes

Have you created the perfect combination of colors, fonts, and backgrounds? You don't have to recreate it for your next project. By saving your creation as a Custom Theme, you can access it instantly in the future.

To save a theme:

1. From the Design tab, click the drop-down arrow in the Themes group.

2. Click Save Current Theme.

3. A dialog box will appear. Type a file name, then click Save.
4. When you click the drop-down arrow in the Themes group, you'll see the custom theme under Custom.


Custom themes have another unique and powerful feature. Any custom theme you save in PowerPoint can actually be used in other Microsoft Office applications, including Word and Excel.
