Set Colors in Your PowerPoint Template
It's important to set a color palette set in your PowerPoint template to match the design elements of the template. More often than you'd think we see beautiful template designs with wonderful color schemes. But the designer stops there. The color scheme of the design isn't added to the color palette for the template. This creates a tremendous amount of disharmony on the slide. It isn't difficult to set the colors. In PowerPoint 2007 and 2010, you can access the color palette by clicking on the Design tab on the ribbon and then clicking on Colors, Create a new theme colors, and then adjusting the Accent colors, etc., to match your template color design.
Ask your designer to provide the RGB formulas for the colors used in the template design. Then simply change them out. If you don't have access to the specific colors used by the designer for some reason, a nice little Add-In called pptXTREME can help you identify the colors. It's an inexpensive utility that we use all the time. Well worth the money.
