Spare tracks on tanks

it a sometimes yes and sometimes no.  No uniformity

Thanks Roy!

This is a huge case of:"it depends". Sometimes you will see them painted in the same camouflage colors as the vehicle, sometimes they are rusted bare metal, and sometimes they are still in the protective coating that is applied at the factory. Using one of those three choices to match your vehicle you will not likely go wrong.

It also depends on how/where the spare tracks are mounted. In cases where the spare tracks were added as "ad hoc" additional armor, they usually got painted the camo pattern right along with the rest of the vehicle.

just an idea but say if the tank crew did indeed paint the tracks the camo color it would be neat to paint some tracklinks in said camo color representing replacement.

Yes, but would best be represented during track replacement or something of the sort. In reality any paint or coating wears off as soon as the track starts moving.
