→Changing the Ubuntu Desktop Theme
Note that themes are not considered to be a system-wide setting. This means that changes made to the current theme affect only the currently logged in user. Other users will still see their preferred theme when they log in.

== Changing the GNOME Desktop Theme ==
The desktop themes define the color and shape of the decorations around the Windows and the color schemes used for the foreground and background of dialog contents. By default Ubuntu uses the Human theme. This is essentially a theme called ''Clearlooks'' with earthy looking colors applied to it. A number of pre-installed themes are also available for selection, and many themes are available for download online.
Themes are controlled by the ''Theme Preferences'' panel accessed by selecting the ''Administration->Preferences->Appearance'' menu option and clicking on the ''Theme'' tab of the resulting dialog. Once selected, the panel appears as follows:

To install a new theme from the list simply select it and click on the ''Install Theme'' button. The desktop will immediately change to reflect the new theme.
== Customizing a Desktop Theme ==
In addition to selecting a theme it is also possible to customize themes. For example, it is possible to change the colors and borders of the Clearlooks theme. To try this, select the Clearlooks theme from the main screen of the Theme Preferences dialog and click on the ''Customize'' button. The ''Customize Theme'' dialog will appear as follows:

Any new selection from the list of Controls will immediately be reflected by the desktop. For example the following screenshot shows the ''Theme Details'' dialog with HighContrastInverse selected:

Colors can be changed by selecting the ''Colors'' tab of the ''Customize Theme'' dialog and changing the color settings for the window borders, text input fields and text selection highlighting.
The window border can similarly be changed by selecting from a range of pre-designed styles using the ''Borders'' tab of the ''Customize Theme'' dialog. The following screen shows the Atlanta Window Border Theme:

Finally, the style of icons displayed in the desktop can be changed. By default Ubuntu uses the ''Human'' style of icons. The following image shows a portion of the desktop showing icons using the Human icon theme:

The following image shows the same desktop icons after the icon theme has been changed to ''Mist''

== Downloading and Installing Desktop Themes ==
If the selection of pre-installed themes does not provide a sufficiently broad selection of choices, there are many more themes available for download on the internet from [http://art.gnome.org/themes/metacity/ http://art.gnome.org/themes/metacity]. Both window border and icon themes are available.
To download a theme click on the theme on the web page and save it to your desktop. A new file should appear on your desktop containing the new theme. For example the following shows the MetaTivo theme on the desktop and ready to be installed:
[[Image:gnome_desktop_icon.jpg]]
To install the theme open the ''Theme Preferences'' dialog, click on the theme icon on the desktop with the left hand mouse button and drag the icon (keeping the mouse button depressed) onto the ''Theme Preferences'' dialog. Release the mouse button to drop the theme. The theme will now be installed into the list of themes as ''Custom Theme''. You will be asked if you wish to apply the theme. To save the new theme select it in the list and click on the ''Save Theme'' button. In the resulting dialog enter a name for the new theme and press the ''Save'' button.
Once the theme is installed into the list of theme the file may be deleted from the desktop. Simply select the desktop icon and press the keyboard delete key.
