User:Cousin Ettolrhc/Sandbox/Fourth Doctor's TARDIS console room (The Invisible Enemy)

After the Fourth Doctor and Leela returned to the main console room, from the secondary console room following some "refurbishment", it was markedly different. 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. (TV: The Invisible Enemy)

According to one account, the control room was badly damaged during the events on Zanak and it temporarily took the form of an English garden with a conservatory, the control console appearing as a sundial. (PROSE: The Pirate Planet) However, it would be reverted back to the design shortly. (TV:The Stones of Blood)

The Fifth Doctor continued to use this design. On orders from the Black Guardian, Vislor Turlough later damaged the Heart of the TARDIS enough to the point of the TARDIS nearly falling apart, (TV: Terminus) leaving the room darker for some time until repairs were done. (TV: Enlightenment)
