 In Hartlepool and Derby taxis are yellow, but both local authorities considered changing the livery in 2019 to reduce costs whilst still allowing taxis to be easily identified.Hartlepool proposed a two-colour scheme with a standard manufacturer colour such as white, silver or black as a base, and retain yellow only on the bonnet and boot, but abandoned plans after a consultation.Derby plans to change to black with a yellow diagonal stripe on each side.
