I seem to remember that one of the display colour schemes in about 88, maybe Andy Wyatt's, had the blue top (with a union jack scheme on the fin). Day to day, it became apparent that the blue topped aircraft were more visible than the previous training command livery - much to everyone's surprise. Steadily, they all became red, white and blue although it was a gradual process. Those 2 are probably the display and spare at Lyneham and yes that is the CFS badge, the display pilot that year was a CFS instructor.
At the same time, more experiments were done on hi-vis and matt black was the best colour, although gloss was easier to maintain. Some Tornado GRIs had various different tail colours too as part of the same testing. Not sure when they all became black though.
