Option 1
First you need to edit the gdm.conf file using the following command
sudo vi /etc/gdm/gdm.conf
you can use gedit also
scroll to where it says BackgroundColor=#123123
replace with your color (or just #000000 for black)
save and exit the file
Option2
A user friendly way is to go System->Administration->Login Window
Once it opens you should see similar to the following screen
Select Local tab and click on next to background colour button
Once it opens you can select your background colour option and click on ok
