An extremely simple resource pack for those who prefer a vanilla-looking game.
Zombies as one of the first hostile mobs in Minecraft, are meant to resemble the default player character "Steve". As such, they are quite literally the Steve skin with green flesh. As time went on, more zombie-type creatures were added to the game such as horses and villagers and even specialty zombies such as husks and drowned - all with different skin tones might I add.
This resource pack unifies the default zombie skin tones, now both default zombies and zombie villagers will have skin similar to the zombie horse. In addition to this, the default zombies garbs have been changed to be similar to the husks, as the bright blue clothing mirroring Steve seems outdated in todays Minecraft.
This resource pack does not change Husks or Drowned, as these were always meant to be drastically different variants of the base zombie.
