Wikipedia definition
3. Green roomA green room in show business lexicon in British and American English is the space in a theatre, studio or similar venue which accommodates performers not yet required on stage. The green room functions as a waiting room and lounge for performers before and after a performance, and during the show when they are not engaged onstage. The origin of the term is often ascribed to such rooms historically being painted green, yet the modern "green room" is usually not green at all.
