If you don’t have time to create your own color scheme for your next presentation – you can use one of the pre-installed color themes in PowerPoint. PowerPoint 2010 comes with 41 color themes ready be applied to your presentation and and your graphics, regardless of what presentation template you are using.
This is a quick guide of the PowerPoint 2010 color themes. Each page displays a color wheel with the accent colors around the dark and light background/text colors in the center and four small mockup slides with the color theme applied. All the color themes are shown on white and the mockup slides have the same light grey slide background for comparison.
