Read more of the description of that Cantina... I have a hard time imaginging that this was a fluke! Rooms with different colors...
The Jekk'Jekk Tarr was divided into five sections, each lit with a different light that represents the environment it simulates. Upon entering, a customer would arrive at the infrared chamber, which was lit with a red light. This area was favored by species that could perceive the infrared, such as the Devaronians and Trandoshans. Adjacent to the west of this chamber was the yellow, arid room, designed to simulate the harsh climate of worlds such as Ryloth and Sriluur. Because of this, this chamber was frequently inhabited by Twi'leks and Weequays alike. To the east of the infrared chamber was a green room of particularly toxic gases. A second toxin room lay to the north of this, and both areas were almost entirely used by the insectoid Gand only. It was likely that the gas in these two rooms was ammonia from their home planet Gand. The fifth chamber was non-toxic and contained no harmful fumes even to Humans. It was a private lounge used by the Quarren Exchange crime lord Visquis, and thus it was locked to anybody but Visquis and his servants. In his lounge was the entrance to his secret headquarters, which contained a dimly-lit maze with lethal gases and a jamming system to insure that datapad maps were rendered useless.[1]
