Color Management

GNOME color manager has been integrated with the GNOME Control Center. It allows you to calibrate your displays using hardware calibration devices (Such as the Pantone® Huey™) and it also allows you to calibrate cameras and printers using a variety of color swatch cards. The monitor profile viewing tool provides a rich set of tools that allows you to more fully understand the effect your chosen monitor profile will have on the on-screen and print display of colors using your system.

GNOME 3.2 introduced a new contacts manager called GNOME contacts. It is integrated with the GNOME 3 search system such that you can search across your contacts in the same place you search for applications and documents.
