PowerPoint provides a variety of design themes, including coordinating color schemes, backgrounds, font styles, and placement of placeholders. Using pre-designed themes makes it easy for you to change the look of your presentation quickly.

Follow these practices for best results
A theme is a collection of specific fonts, colors and slide layout. When any of these elements is formatted manually, that formatting overrides the theme. For example, if your presentation uses the Courier font and you manually format some of the text as Tahoma, reapplying or changing the theme will not affect the text that is Tahoma.
To return manually formatted elements to the theme settings, see the following steps.
Restore a font to the theme font
Each theme has two sets of fonts, one for headings and another for body text. If your text is a heading, use the Theme Headings font. Otherwise, use the Theme Body font.
Select the text that you want to change to a theme font.
Tip: You can hold down SHIFT to select more than one text box or object that contains text. If you cannot select an object or text on a slide, modify the slide master.
On the Home tab, under Font, click the arrow next to the font box.
To change text to a theme font, click the Theme Headings font or the Theme Body font.
A check mark shows that the Theme Headings font or the Theme Body font is selected
Restore theme colors to objects
If you apply a theme and some objects do not change to theme colors, they probably have manual formats applied.
Select the object for which you want to restore theme colors.
On the Format tab, under Shape Styles, click the arrow next to Fill, and then click the color that you want.
A theme color, a brick red in this example, is selected for the object
Restore theme layouts
If you apply a theme and some slides do not change to theme layouts, the layouts were probably changed manually. For example, if you move a heading to a different place on the slide or change the position of a table, those items have manually formatted layouts that do not change when the theme changes.
Click the item that you want to restore to the theme layout, such as a repositioned heading.
On the Home tab, under Slides, click Layout, and then click Reset Layout to Default Settings.
