3rd doctor control room

The Third Doctor's console was pale green (TV: Doctor Who and the Silurians, Inferno) and later changed its entire design including the time rotor. (TV: The Claws of Axos)

The Third Doctor briefly changed the walls of the console room, adding concave "bowl" shaped structures over the regular roundels, with edges that jutted out from the wall, and featuring shallower, non-backlit roundels for the half-roundels at the tops and bottoms of the walls. One of the roundels served as a replacement for the scanner, a picture appearing in its centre. (TV: The Time Monster) He later reverted to the more traditional design, though with a more visible separation between the roundels and the wall behind them. (TV: The Three Doctors)

The Fourth Doctor continued to use this console room, adding a wall featuring the shallow, non-backlit roundels first seen during his encounter with Kronos at some point during his travels with Sarah Jane Smith. (TV: Planet of Evil, Pyramids of Mars)
