KDE allows you to save the different changes you made to your desktop's appearance in one file, using the Theme Manager in KDE Control Center. Once you have set up your desktop the way you want, click on Create New Theme.... Enter the details you want to give your theme, such as theme name, author, version, etc., then click OK when done. This will add your theme to the list of available themes and save your settings in a KDE theme. A KDE theme (.kth file) instructs KDE on what window decoration, style, or color scheme to use for that particular theme. To add a KDE theme from an outside source, click on Install New Theme... and locate the KDE theme file. Removing a theme is easily done by clicking on Remove Theme. If you made changes to your theme, you have to either create a new theme name for it, or remove the previous version first to be able to use the same theme name.

The following are the settings that are saved and indicated in a KDE Theme:

One very important thing to consider when using or installing a KDE Theme is that it only indicates what settings to use for the above. A KDE Theme includes only system notifications, desktop background, panel background, Konqueror background, and the color scheme in its package. The other components must be installed separately if they do not already come with KDE.

KDE Themes can be downloaded from the Theme-Manager subsection of kde-look.org, under the Themes/Styles section.
