Hi Steve,
Early French aircraft were mainly clear doped linen (CDL) or aluminium silver. Later some aircraft types were camouflaged by the different manufacturers, as with the early Spad V.II and later Spad V.III.
Each manufacturer chose slight differences to the standard camouflage style, roundels and even the style and positioning of the aircrafts serials numbers.
Spad's were produced primarily by Bernard, Bleriot, Kellner and Spad and each style, where applicable, is reflected in the Spad skins in WOFF.
