Iron Golems Wear Collars

Let all Iron Golems players spawn with having a Collar.

As a Hardcore player, I need something visual to help me distinguish between loyal Iron Golems I created vs the Villager spawned ones. The fact that they're indistinguishable from each other unless you attack them makes it not worth it to use them in colorful ways in a Hardcore mode where the goal is to not let anything potentially kill you. The only solution is to attach a lead on the player-made ones but that's too "involved".

Let all Iron Golems spawn into the world with a customizable Dyable Collar, like wolves after you tame them. Or just any other visual indicator to distinguish the loyal ones from the neutral ones without having to download a mod. Please and thank you, from a hardcore player.
