There were some complete aircraft that went through various colour schemes. The Wessex of 72 Sqn comes to mind with a sky blue one, an overall black one and various shades of camouflage. The two tone green in lieu of green and grey was the outcome.
That red and white training aircraft were painted black was the decision based on information provided by a psychologist. Never quite agreed with that one and the system must also have been unimpressed which is why DHFS and Police helicopters have large yellow elements in the colour scheme.
Air Defence grey (Matt) in lieu of bare metal makes sense but soon changes with reverse thrust and groundcrew boots making the airframe a mess. Matt paint is also short lived compared to gloss. Even the Lightning went through phases: Bare metal > camouflage grey/green > Two tone grey single tone grey. The short lived phase of adorning squadron colours on the tail was an exploitation of formal recognition that the air to air collisions that had occured were inevitable. The most dramatic was the two Harrier GR3 attacking Otterburn from differing direction in theory separated by a few seconds but in reality (and sadly) proving a fatal mistake when they hit each other in a most dramatic fashion.
High Intensity Strobe lighting has probably contributed more to Flight Safety then any colour scheme, and an adoption of the american green strips that are bound to have a name, but I do not know it.
