what's the best color pallete for modern tanks such as Leopards, Leclerc, Abrams, Challengers, and etc...

Im looking for the best patterns because i will release the following tanks soon, it will have track mods so make sure to have it (lazy to make one manually)

as usual, its not original builds, i rebuild some of them and reduced or recreate some parts, i borrowed some stuffs to others.

thats it thank you.
