How can you change the background color of a slide?

Changing the background color of a slide in PowerPoint is effectively achieved by using the "Format Background" option. When you right-click on the slide, the context menu that appears provides access to various formatting options, including "Format Background." This feature allows you to customize the background extensively, offering options such as solid fill, gradient fill, picture fill, and texture fill, along with the ability to choose specific colors for your slide's background.

The other options, while related to different aspects of slide design, do not specifically address the direct alteration of a slide's background color. For instance, the "Color" tool located in the Home tab focuses more on text and shape colors rather than the slide background itself. The "Design" tab enables selection of overall themes, which can influence background styles but does not provide the granularity needed for custom color changes. Lastly, applying a layout merely organizes content on the slide without specifically allowing for background color adjustments. Thus, the most precise method to change the slide's background color is indeed through the "Format Background" function after a right-click on the slide.
