Themes and Background Styles
You can also modify the current theme colors, fonts, and effects. For example, if you like the Urban theme but would prefer to use more red in your presentation, you can change the colors of the theme and create a new custom theme. If you would prefer to use the Verdana font style so your presentation font will match your company logo and materials, you can modify the font combination and save it.
PowerPoint themes are powerful because they allow you to create professional-looking slides easily. The option to modify these themes makes it an even more robust and powerful tool because you can customize themes based on your needs and preferences.
