When you open PowerPoint2013, you'll see a built-in color slide design (called a "theme") that can be applied to your presentation.
Select a slide theme
Tip These built-in themes are suitable for Ukun (16:9) and standard screen (4:3) presentations.
Select a color variant, and then click Create.
Color variations
If you change your mind, you can always change the theme or variant on the Design tab later.
The production method is as follows:
On the Design tab, select the theme that contains your favorite colors, fonts, and effects.
To preview the appearance of the current slide that has the theme applied to it, rest the pointer on the thumbnail of each topic.
To apply another color variant of a specific topic, select a variant in the Variations group.
Variant
These are the tutorials for PowerPoint2013 slides to apply colors and design themes to friends who are not good at PowerPoint but are in dire need of this software.
