I've enquired throughout various modelling communities to find out the proper name for 'raspberry ripple' paint scheme without much luck, so I tried F.A.S.T (Farnborough Air Sciences Trust) museum, today I got a brilliant reply from David Wilson, museum trustee
Dear Miko Lee,
Your query about the “Raspberry Ripple” colour scheme has been passed to me for action. At the time of its introduction (mid 1970s) I was the Aircraft Servicing Manager (ASM) at A&AEE Boscombe Down and that included ETPS. I also worked very closely with my opposite numbers at RAE Farnborough (which included RAE Bedford) and at RSRE Pershore (the airfield for RSRE Malvern).
The official name of the scheme was “MoD (PE) Conspicuity Colour Scheme”
(The PE stands for ‘Procurement Executive”)
The rules under which we operated were drawn up by Director, Flying (D/Flying) and his directorate was responsible, among other things, for policy on flight safety matters in the various establishments in the Procurement Executive.
The background to the introduction of an aircraft colour policy is that there had been a fatal accident between a low flying Phantom and a crop spraying aircraft; neither pilot saw the other aircraft. As the trials involving aircraft on trials work required flying “randomly” and certainly avoiding commercial flying and air corridors, the directorate decided that we should make all our aircraft as conspicuous as possible.
A trial was conducted at RSRE Pershore (long since closed) using large models of various aircraft shapes and the conclusion they came to was that for maximum conspicuity (ie. standing out from the background) was to have the topsides painted white, the lower surfaces painted a particular shade of darkish blue and the tail section and various other bits painted red. The red applied to the tail section involved a very stark change of colour to red.
I am working from memory on the issue of the particular shade of blue paint to be used on the lower surfaces of the aircraft but I recall that what was specified was a British Standard colour which I think was called Oxford Blue. It was the colour that the Beagle Bassett aircraft which the then Prince Charles (now King Charles) had used whilst training to fly a twin engined aircraft. The odd thing about it was that it was NOT the same as the blue already being used extensively by the Royal Air Force and was classifies as being “Not in vocab” This means that instead of using the blue paint available in the standard lists of spares, the blue paint for the conspicuity colour scheme, although very similar to the standard available blue, had to be bought in relatively small but expensive quantities.
When it came to deciding exactly which parts should be painted which colour, although we at Boscombe Down stuck to the letter of the scheme, the RAE Farnborough aircraft had the scheme applied using the natural lines of the aircraft. I have no reason to suppose this made the aircraft less conspicuous and it certainly made the aircraft look very smart.
I do not recall hearing the term “Raspberry Ripple used at Boscombe Down but by the time I became involved with the FAST Museum (about 2000) it was in common usage and I think it invoked a good deal of attraction and enthusiasm. As the PE was reduced in size, the aircraft began to reappear in aircraft collections around the country and indeed around the world. Whenever I see an ex PE aircraft, it invokes a high level of interest, nostalgia and enthusiasm.
I hope that has answered your question; I would be happy to try to get more specific details for individual aircraft if you need more help in your quest to be accurate with the colours; do come and see us again as we have done a great deal of work to improve our displays - you will not be disappointed.

I'm super grateful to the staff and trustees of FAST for the work they do in preserving our aviation heritage and taking the time to reply to enquiries from the likes of me!
