Changing a document theme or color scheme can be confusing. To change your current theme, switch to a different one, or create a new theme, you use slightly different commands, depending on which app you are using: Excel Word TIP: The first group of colors are the colors in the current theme. To create your own color, click More Colors, and then pick a color on the Standard tab, or enter numbers or select a color on the Custom tab. TIP: To return to the original theme colors, click Reset before you click Save. Excel Word TIP: The top fonts are the fonts in the current theme. Theme effects include shadows, reflections, lines, fills, and more. While you cannot create your own set of theme effects, you can choose a set of effects that work for your document. Once you’ve made changes to your theme, you can save it to use again. Or you can make it the default for new documents. NOTE: The theme is saved as a .thmx file in the Document Themes folder on your local drive and is automatically added to the list of custom themes that appear when you click Themes. After saving your theme, you can set it so it’s used for all new documents. Apply your custom theme to a blank workbook and then save it as a template named Book.xltx.

You can also change the Office theme. The Office theme is the color scheme for your entire Office program, while document themes are more specific (they show up in individual Word documents or Excel spreadsheets).
In addition, you can add a pattern to your Office program, by changing the Office Background.
