RN Ptoctors

I am trying to find an unusual British military scheme for a Percival Proctor and was wondering if anyone can help? I know the Royal Navy used them and have found this photo, but I have no idea what colour it was or serial?
Does anyone know or have any photos of Royal Navy Proctors or even of RAF machines that are not silver overall or camouflaged? Apparently there was an RAF Air Commodore that had one for his personal use painted ‘pale metallic blue’ overall, but I can find no photo. Over to you?

****** Air Vice-Marshal Sir Ralph Sorley had a Mk 1V as his personal ‘Hack’, I’m not sure what colour it was though, or where it was based.
