Verdun camouflage seen on early Nieuports (10, 11, 12, 15, 17) was made of oil paints sprayed with use of early spraying devices.
Late Nieuports (27, 28) carried "butterfly" camouflage painted with brush. Metal and wooden surfaces were painted with use of oil paints while fabric was painted with use of pigmented and aluminized dope (that is dope with color pigments and aluminum powder added).
