Green Room: The Green Room is similar in size and decoration to the parallel white room, except for the color of the tapestry that is green, and has a mirror over the fireplace. The social function of the room is for the poorest people of the city, or students from the nearby university to meet. Students knew that in this room they could stay undisturbed for warmth during the winter, to make conversation or to study without a waiter disturbing them. Hence the Italian expression “"essere al verde"” (literally - "to be green"), signifies "to be penniless", or "to be broke".
