Why don't the revelers go into the seventh room?

"The Mask of the Red Death: A Fantasy" was a short story written by Edgar Allan Poe and published in 1842. In the story, each room corresponds to a different stage of human life and this is represented by different colors. The Seventh Room, for instance, is described as a dark place covered in black velvet tapestries that were terrifying and quite unpleasant to the eye. The revelers don't go to this specific room because its black color is associated with death and they were afraid of it.
