The document discusses set design considerations for a play called "Wintertime". A proscenium theatre would be well suited as it allows for easy changing of sets between scenes of a cabin and a lake. The cabin set would include modern furniture with soft edges, open windows, and framed pictures to set a warm mood. Lighting would start warm but get colder throughout to match the changing themes, using yellow, white, blue, red, green colors to set the right atmosphere for each scene and enhance emotions. The lake set would have a backdrop of forest and cabin illuminated in contrasting warm and cold colors to depict the cold winter weather.
