Like a sprawling, misshapen Christmas tree the lights of Sector Twelve General Hospital blazed against the misty backdrop of the stars. From its view- ports shone lights that were yellow and red- orange and soft, liquid green, and others which were a searing actinic blue. There was darkness in places also. Behind these areas of opaque metal plating lay sections wherein the lighting was so viciously incandescent that the eyes of approaching ships' pilots had to be protected from it, or compartments which were so dark and cold that not even the light which filtered in from the stars could be allowed to penetrate to their inhabitants.
