Whenever you launch PowerPoint, you may typically see a single slide with a white background. Or if you open any of your existing presentations, the background of your slides may be in a different color depending upon the Theme that the presentation is based upon. You can always change this slide background to a picture, a solid color, a pattern, or even a gradient. However, before you think of all those options, do explore the twelve background styles that PowerPoint offers for every presentation by default. These styles are all coordinated and also designed to work well as a set of complementary backgrounds.
