London licensed taxis are called ‘black cabs‘. However, the technical regulations for the London cabs called ‘Conditions of Fitness‘ are not specifying black as the only colour.
So the taxis on London streets that used to be traditionally black are allowed to be of different colours. Some traditional technical requirements stand however. These are: separate passenger and driver compartments, high internal headroom, and ability to turn 180° within the 28 ft limit.
