Another unit which used pink as a base colour was the Long Range Desert Group (LRDG) LRDG Uniforms and EquipmentAgain, concealment, especially at dawn or dusk was one of the objectives.

The pink disguised the aircraft against the cloud base but if there was insufficient cloud cover the mission had to be abandoned as the colour made the aircraft highly visible when viewed from above. 

In early 1941 the German warships Gneisenau, Scharnhorst and Admiral Hipper put into harbour at Brest. No 1 PRU was given the top priority task of photographing the port three times a day. To accomplish this, whatever the weather, pairs of Spitfires took off from St. Eval, Cornwall, and flew to Brest independently. A blue painted type C or F would photograph the port from high altitude if the skies were sufficiently clear ; a pale pink Spitfire took photographs if there was cloud cover. Six-tenths’ cloud was termed ‘no-man’s land’ figure. Too much for high altitude photography to be successful and too little to conceal a Spitfire at low altitude. Fighter units and flak batteries defending Brest soon became aware that regular flights were being made to photograph the harbour and losses mounted. Gordon Green. “During the early missions to cover Brest we lost about five pilots fairly quickly. After the first couple had failed to return, the Flight Commander, Flight Lieutenant Keith Arnold, asked Benson to send some reserve pilots. They duly arrived. Both took off for Brest that evening and neither came back. That was a very sobering incident.” These missions where called ‘dicing’ from ‘dicing with death’. 

The PRU obtained its paints directly from the manufacturers, in particular Titanine. PRU Pink was never included in the RAF Vocabulary of Stores section 33B or any of the wartime MAP colour standards booklets. Any post war colour bearing that name may have been developed separately by the RAE and so may be similar but the not the same as that used by the PRU during the war. 

Green Camotint was named Sky by the RAE when it was adopted by the Air Ministry
