Above the dance floor hang several concentric "rings" that recess into the ceiling from outside to inside, with the largest ring measuring across and the smallest, most recessed circle located in the center of the other rings. There is a chandelier hanging from a brass pole in the middle of the central circle. This is the largest of the three chandeliers in the Rainbow Room, although a fourth chandelier formerly hung above the east alcove. Both indirect lighting and crystal light fixtures on the walls illuminate the space. The famed lighting designer Edward F. Caldwell & Co. designed the room's original four chandeliers. There are mirrors in the alcove, the eastern and western walls, and around the stage, which were intended to reflect the activity of the room in both the figurative and literal senses.
