Wayne and Ernest are almost correct. Battle of France concluded in May 1940 and the correct scheme for a IV Ausf C with the 1st Pz Div in France would be the 2/3 Dunkelgrau and 1/3 Dunkelbraun scheme. No green involved under this scenario. The order to switch to just plain dunkelgrau schemes (which we know as panzer gray) came down in June 1940 and stayed in effect until Feb '43. HTH!
