Following the merger, most of the fleet progressively adopted Air UK's new blue, white and red colour scheme. Originally, this featured a predominantly blue fuselage with a white-red-white strip across the windows and a white roof. The tail was also predominantly blue, apart from the "Air UK" logo. However, the Civil Aviation Authority (CAA) disapproved of this predominantly blue livery, arguing that it could potentially pose a safety hazard for other aircraft as it was difficult for other crews to see the blue aircraft against a blue sky. To address the CAA's safety concerns, Air UK decided to amend its original colour scheme by opting for a hybrid blue-and-white scheme featuring a blue fuselage and a white tail.
