The background color is set to be similar to the default background in Ubuntu. This is because there is a race between the X window being shown, and the greeter process drawing to it. The default gray caused a visual flash to be seen if the greeter was too slow in drawing the first frame, it's just less noticeable with it set to purple.

There is a /etc/lightdm/lightdm-gtk-greeter-ubuntu.conf file, containing the following: [greeter] background=/usr/share/backgrounds/warty-final-ubuntu.png The named background file does not exist. (Not even the /usr/share/backgrounds/ directory is present on this system.) When LightDM starts up, the background is set to a strong magenta color (looks like #FF00FF) that is ugly as sin. A more attractive fallback (black? grey?) would be helpful, and better care should be taken in the configuration not to name a missing file in the first place.
