In this example we have used the Red Project Portfolio PowerPoint template that you can download from our site. In this article we will show you how to create and edit a custom color palette in order to make PowerPoint themes that can be easily edited to match any other color combination. Then, switching the Theme Color palette during design time you can easily give your presentation a different look. While designing PowerPoint templates you can take advantage of the Theme Colors feature to create or use pre-defined color palettes for your presentation.
