Change background colour of textieditor 'gedit'

Hey,

I have trouble to change the background color of the standard editor ‘gedit’, or more precise the editor that comes up if I type in

> gedit

Nearly every online help states that one should be able to change the color (often labelled as theme, scheme, etc.) via the preference field. However, I cannot find such a button or field… Does anybody have an idea on how to switch the theme?

I would appreciate your help,
Niklas

Hi,
I assume you use GNOME 3, please correct me if I am wrong.
To access Preferences click on the arrow next to the application name on the GNOME top bar, you will find “Preferences” in the drop down menu.
