In the late 60s a Tech Grade Civil Servant, interested in camouflage, tried to find the RAF policy for camouflage and found there was no consistent policy. Was the purpose to conceal them on the ground or inflight? If inflight, on what mission or terrain.
It was done on a Looks about right basis which was why Middle East TacT had a similar scheme to the V-Force but brown on brown with a white aim here cockpit on a one style fits all basis.
He trialled a water based application and concealled a C130 on the Kingsfield Strip in Cyprus. IIRC it was painted pink overall. I believe his work led to Harriers assigned to AAFNorth getting temporary white dazzle and RAFG Lightnings green overall for ground concealment.
Of the Mk 1 Nimrod it was observed that they were painted just like sea birds only upside down.
