Green Room

All the answers are plausable -even the one where actors used to take off all green clothing prior to going on stage - because green flags were used for cueing?????? well that's a bit far fetched - the one I believe that is more likely is;- as most performances orginaly were not in a theastre but on the village green's - As the temp staging would have been the backs of wagons and/or quickly setup staging of timber. Along side was erected a an area made of canvas, bed sheets or what ever - if they could aford it a tent, so the troupe and players could have some privacy. However in most cases they did not go to the level of installing a floor - this was the green grass - hence the green room came into being.Take it for what it is worth, so long as we know what we are taking about?- as for a painted room. it would have more likely have been Whitewashed, because of the availabily and costs at that time.
