Once again Ellen gives us a trick that shows how a little tweak can make a big difference in the attractiveness and functionality of your slides. You can easily leverage the power of Themes without doing major overhauls to your masters. Transparency is your friend.
Of course this method works for any background, not just textured ones. You could even easily customize a presentation you are presenting to a business to make the overlay color one of their brand colors or if speaking at a university you could make it one of the school’s colors. Small personalizations can help draw the audience in.
