Working with pictures in PowerPoint 2013 can be so much fun and fulfilling at the same time. One of the coolest options is to recolor the hue of your entire picture so that it looks almost like a duotone picture. You have already learned how to apply corrections to your inserted pictures — and this Color option can help you do more with your pictures. Be aware though that although the option itself is called Color, it does not work like a coloring book — rather it changes the overall hue color of the entire picture. This option also allows you to saturate color values, change the overall color tone, and do more.
