William...in the Osprey (my bible) Nieuport Aces of WWI, (the) Norman Franks says " Quite often the RFC Nieuports retained the silver-doping the French used, although others were camouflaged, some in the French fashion, or in the standard British khaki-green." ...quite good enough for me...I'm absolutely accoutering one of mine in PC10, you bet....and I'm sure I will love it.
