Changing the Color Scheme in Gedit

I find looking at a white background and black text a little daunting in Gedit, however in Ubuntu 7.10 (Gutsy Gibbon), you can easily change colour schemes and save your eyes. To change schemes:
In Gedit Go to Edit –> Preferences.
In the Preferences dialogue click on the Font & Colours Tab.
Then choose a scheme to suit you.
