Hi Guys, So I have several CME Conference Lectures (slides made in PPT). Unfortunately, I guess these presenters love color, and so all slides are in a blue background with white text or some variation thereof. Personally, I like to have a print out of the slides when I am reading/preparing for my future cases. etc. and so I physically print these slides out. Unfortunately, the unnecessary background color is an unnecessary burden on my printer, and so I was wondering how I can change the the background and text in one shot so I don't have print out the unnecessary color. I have tried trying to change the background from within powerpoint, but because the text is often in white, this causes the text to "disappear" on a white background. The only way to get the text back is to change the text color on a slide by slide basis. This is fine if the presentations are short, but most of these presentations are 200+ slides. I was hoping there is some trick either in powerpoint or keynote to be able to change slide themes (such that background and text can change in one shot). Thanks in advance to those who can help!
