Wilhelm Schillings Gelbe 3 has been a popular subject for profiles and models as a colour photo has been around for ages. The photo doesn't show the whole aircraft though so profiles have been speculative. Black and white photos have appeared and show that there's more to this scheme than previously thought.
It cleary has at least three colours on the fuselage. A light colour has been used for meandering lines on some of the darkest segments of camo. It can be seen on the starboard wing as well. On other aircraft in similar schemes the lightest colour is also used for a segment or two in the camouflage pattern. Other JG54 aircraft shows various browns and possibly RLM 02 so the actual colour is impossible to know. Also, despite the new photos, the camo from fuselage fram 7 and backwards is still speculation based on other contemporary JG 54 aircraft.
Profile 1: The first photos of this aircraft shows it when Schilling celebrated
returning from his 500th combat mission. Almost the entire engine
cowling is painted in the medium colour that we know from the colorphoto
to be quite a bright green colour.
Profile 2: Two pictures taken during what appears to be some light repairs shows that new segments of colour has been added on the enginecowling. (The aicraft was damaged twice in September according to the loss lists)
Profile 3: The broad yellow fuselage band has been added and the rear part of the canopy has been replaced by one in original grey that appears to be RLM 75.
