This is, IMHO, the BEST Power Armor Paint mod

My favorite from that selection is the Flecktarn (this is only mod that offers flecktarn)

BUt the brtish ones are good too, especially british winter camo in a winter landscape)

This makes our Power Armors looks less steampunky and more brutal and like real tools of war.
