A theme is a collection of settings which modifies or controls the appearance of a desktop and its components in a consistent manner. When a theme is applied, the system simultaneously modifies various desktop components to achieve the required effect. For example, if you apply a theme that increases the font size across the desktop, it also modifies the panel size and the icons on the desktop for optimum compatibility with the font size.
A theme contains the following settings that affect various parts of the desktop:
Determines the visual appearance of all windows, applications, panels, and panel applications. It also determines the visual appearance of the GNOME-compliant interface items, such as menus, icons, and buttons. Some Controls options that are available in the desktop are designed for special accessibility needs.
Determines the color scheme used to draw controls. If a theme does not support this feature, its color scheme is fixed by the theme's designer and cannot be changed by the user.
Determines the appearance of frames around windows only.
Determines the appearance of icons on panels and on the desktop background.
Determines the shape, color and size of the mouse pointer.
