Modify PowerPoint theme elements to mix and match colors and fonts. Learn all about using the PowerPoint modify theme feature here.
PowerPoint makes it easy to apply new theme effects, which can quickly change the appearance of shapes in your presentation.
Applying new theme effects will change different shape styles from the Format tab when editing a shape or SmartArt graphic. It's important to note that this change will only apply to shapes using the Subtle Effect, Moderate Effect, and Intense Effect.
