The sanatorium's overall aesthetic projects a sense of decay and gloom, heavily influenced by shades reminiscent of liver. The dark woodwork and deep brown leather chairs contribute to a heavy atmosphere, while the walls, once bright, have faded, plagued by mildew or dampness, which gives them a sickly appearance.

The flooring, a mottled brown linoleum, reinforces this impression of deterioration, encapsulating the somber and oppressive setting. This description immerses readers in an environment that reflects not just physical neglect but also the emotional struggles faced by the characters within the narrative.
