One of the worst things that you can do to your PowerPoint presentation is to add a busy, multi-colored picture background to your slides. However, people do that all the time and in the process, they compromise the subtlety and contrast of any content on their slides. So why do they do so? Most of them look at the picture in isolation to the entire picture. As a picture, their chosen content may appear awesome. However, place the same picture as a backdrop for text, charts, shapes, or other slide objects, and you will realize that this just doesn’t work. Fortunately, you can make the visual noise in any picture more subtle by recoloring them within PowerPoint.
