| GREEN ROOM | Room close to the stage for the actors to meet and relax. According to the 1894 edition of Brewer's Dictionary of Phrase and Fable the common waiting room for performers is so called "because at one time the walls were colored green to relieve the eyes affected by the glare of the stage lights." However, the Oxford English Dictionary cites the earliest usage of the term as 1701, a period when stages were lighted by candles and oil lamps (the English did not develop limelight until the late 1830s), so Brewer's supposition seems misplaced. The term was also used to denote a room where undried pottery was stored before being fired. It's possible that by extension this meaning was applied to the backstage room for actors waiting to go onstage. | |
