>>44752967I never played Pokken buut, Bulbapedia says those were: Virtual Paint. One of the functions of a battle capsule (a device that sets up an arena for battle). When two Pokémon of the same species battle, virtual paint is applied to temporarily change the color of one of the combatants, making it easier for spectators to follow the action.
I'm looking for something a bit more like hair dye which would be visible outside of those battle arenas.
