Your slide background might not seem too important at first glance, but think about the presentations you’ve seen recently. Have any been hard to read, boring, or uninspired? The background can have a lot to do with that.
Good presentations are interesting without being overpowering and provide a good contrast with respect to text color and size so that you can read what’s on the slide without difficulty. You can change the slide background easily in your PowerPoint presentations or use the ones the program applies when you choose a theme. You can also modify an existing background to add your own special touches such as a company logo or an image that you want to appear on every slide.
