4th doctor control room

After the Fourth Doctor and Leela returned to the main console room following some "refurbishment", they began to use a markedly different console room. The walls of this room were a light shade of grey, and the roundels were significantly shallower, with a yellowish-beige design mimicking the ones found within the secondary console room. Corrugated grey columns were placed in various corners of the room, and the monitor was changed to a large, flat screen beneath an aperture that opened similarly to an eye, resting between the exit and the door leading further in.
