chunk: One night, Prospero holds a masquerade ball to entertain his guests in seven colored rooms of the abbey. Each of the first six rooms is decorated and illuminated in a specific color: blue, purple, green, orange, white, and violet. The last room is decorated in black and is illuminated by a scarlet light, "a deep blood color" cast from its stained glass windows. Because of this chilling pairing of colors, very few guests are brave enough to venture into the seventh room. A large ebony clock stands in this room and ominously chimes each hour, upon which everyone stops talking or dancing and the orchestra stops playing. Once the chiming stops, everyone immediately resumes the masquerade.
