Sir, on this issue i have read some sources to support the thesis that camouflage was left to end user unit commanders to account for mission requirements. One source is the “Tank Encyclopedia “ which, on subject of Jagdtiger says “ Paintwork
From the end of 1944 onwards, the exteriors of Jagdtigers produced at Nibelungen were painted in a red anti-corrosion primer which was then painted over in varying quality with dark yellow and green. The interiors which had previously been painted an ivory colour were left in the red primer colour instead to save time. Camouflage was left to units to apply in the field once they had received their vehicles.”
As a US Marine no longer on active duty i can at least attest to the military postulate that camouflage is always dependent on terrain and weather . And like fighting positions it was always being upgraded. German armor units in the Western theater of the European theater were always excellent at camouflage. sadly US units were slow at catching on, right up to learning the hard way that the white star on the sides of the turret were excellent bullseye’s for German gunners
