Adding Color to a Slide Background
What if you don’t want the entire presentation to have a colorful or graphic-based background? You have the flexibility with Microsoft PowerPoint 2007 to only add background to selected slides. This is a great tool to put specific emphasis on certain slides of information rather than the entire presentation.
To add color to the slide of your choice, click on the slide that you wish to add the background color to. If there are multiple slides in which you want to highlight with color, click on a slide, then press and hold down the CTRL key while you click the additional slides.
The process of adding a solid colored background is the same for singular/multiple slides as it is for the entire presentation. You would click on the Design tab that will take you to the background tools. From here, you would click on Background Styles and then on Format Background. When you reach this step, you would click on Fill and then on the radio button next to Solid Fill.
To select the color palate, click on the icon. The variety of colors can also be customized by clicking on More Color. Please note that custom-selected colors that are on the Standard tab are not updated if you decide to change the document theme at a later date.
From this step, you can adjust the strength of the color by adjusting the background transparency by moving the slider to the desired brightness and opaqueness percentage. To apply your selection to the slide(s) that you selected, you would then click on Apply to All and click Close.
