So currently working on the camouflage.
As previously mentioned, the base colour is Citadel Zandri Dust.
The green pattern was painted with Vallejo Russian Uniform Green. The brown pattern is Citadel Mournfang Brown,
Zandri Dust is a lot more yellow by eye.
Here is the Tank Museum Tiger II with the production turret (the one with the prototype turret has no Zimmerit and no camouflage).
