Good day everyone,
As mentioned in a few developer Q&As in the months leading to now, enhanced customization is now being tested, and looking to come out in December with 9.21. This includes being able to paint individual parts of the tank, scaling camo patterns, and some changes to the emblem overlay interface.
No fear though for those who prefer the more historical aspects of the game (such as they are). There is apparently an in-game option to disable non-historical camouflage.
Also of note, and as also mentioned in various Q&As, there will likely be more customization possibilities coming in the future. This “3D” customization will bring customization camo nets, helmets and various other bits hanging off the tank. None of which will affect gameplay or armor models.
