Change all slides that were not set up using slide master
How do I remove the background color or change to white in all of the slides when my teacher must have made the presentation without using the slide master? Do I need to delete each one individually? Or can I create a new master or theme and apply? It appears that she has a large text box that is colored in. Sure the slides are pretty, but I hate wasting ink.
I am attaching a few slides from the powerpoint for reference.
