The default background color in PowerPoint is white. You may want to swap that white for a different shade so your slides feel more visually engaging or match a specific theme. Here’s how to change the background color in PowerPoint.
1. Open your PowerPoint presentation. Go to the “Design” tab on the ribbon.
2. Find the “Format Background” option under the “Customize” section.

3. In the “Format Background” pane, select the “Solid fill” option under “Fill”. Click on the color bucket icon beside the Color option. If you’d rather match a color already in your slide, the eyedropper next to the color bucket lets you sample it directly.

4. Pick the color you want from the popup list.

5. After selecting the color, click “OK”. Your new background color will be applied to all slides in the presentation.

Conclusion
As you can see, changing the background color in PowerPoint is quick and easy. Experiment with a few different shades to find one that suits your slides. You can always revert back to the default white background if you don’t like the new color.
