Not a theatre or period I'm familar with, but I would think the green would be the lighter of the two early war colours, RLM 71 Dunkelgrun. I'm only basing this on how the RLM 70 Schwazrgrun was replaced in other schemes, for example in 1940, on Bf109E's, where RLM 02 was used instead. Also, not that it's a good guide, the colour doesn't look that dark on the painting guide from the box.
