The Tango Desktop Project is an open-source initiative to create a set of design guidelines and to provide a consistent user experience for applications on desktop environments. The project has created a set of icons known as the Tango Icon Library, which is described as a "proof of concept". The Tango Desktop Project is a project of freedesktop.org, and is closely linked with other freedesktop.org guidelines such as the Standard Icon Theming Specification.

Objectives
The objective of the project is to allow software developers to easily integrate their software, in terms of appearance, with the desktop computer. The visual inconsistencies that arise from different desktop environments (KDE, GNOME, Xfce...) and custom distributions make it hard for third parties to target Linux. Ideally, any project that follows the Tango guidelines will have a look and feel that matches well with other icons and applications that follow the guidelines.
The style does not aim to be visually unique to distinguish itself. Instead, a secondary aim of the project is to create a standard style that makes applications look appropriate running on operating systems common at that time, such that ISVs will find that their application does not look out of place on Windows XP, Mac OS X, KDE, GNOME, or Xfce.
Apart from the visual guidelines, the project aims to provide a set of common metaphors for the icons. Tango follows the Freedesktop.org's Standard Icon Theming Specification and actively develops the Freedesktop.org's Standard Icon Naming Specification, defining names for the most common icons and the used metaphors.
Many free software projects, such as GIMP, Scribus, and GNOME, have started to follow the Tango style guidelines for their icons. Also, ReactOS and Mozilla Firefox 3 uses Tango icons when it is unable to find the user's installed iconset, and also for icons not covered by said iconset.
It is also possible for proprietary closed source applications to use Tango Desktop Project icons. Examples highlighted by the Tango Showroom include VMware Workstation 6 and Medsphere OpenVista CIS.
History
The Tango icons were originally released under a copyleft Creative Commons license (Attribution-ShareAlike), but were released into the public domain in 2009 in order to make it easier to reuse them.
