Familiarize yourself with the role of color schemes. It will help you understand what is happening with the background color of your slides
- Switch to the slide master view (or, if you wish to change only one slide, the slide view).
- Modify the color scheme that is in effect so that the background color is the color you desire.
- Choose Format → Background.
- Click the drop-down arrow and select Automatic or click the first color in the first row on the palette, which is the background color from the color scheme.
Choosing Automatic (or the first color on the first row of colors) ensures that the background color is the color scheme's background color. If the color isn't correct, select it and then modify the color scheme's background color.Do not click any other color in the first row of colors. Unless you totally understand the impact of using a non-color scheme color on the background, do not click any other color in the drop-down menu.
- Click Apply to change one slide or master, or click Apply to All to change all slides.
- If you are changing a slide master, the Apply command changes the master and all slides based on that master, but any slide that has had a background applied directly to it will not be changed. Apply to All changes all masters and all slides, even those that had a background applied directly to them.
- If the result isn't what you expected, one of two things may be happening.
- Most likely, the color scheme is not correct--return to step 2
- It might be that there are objects on the slide that have been "sent to back" that are blocking the view of the actual background. Delete any objects that are interfering with the background of the slide master.
- If you are changing the entire presentation, you may wish or need to repeat this procedure on the title master.
