The 2019 Joker Makeup for Arthur Morgan is a mod that lets you add the iconic face paint to all of Arthur's face textures.

What do you get when you cross a terminally ill loner with a gang that abandons him and treats him like trash? I’ll tell you what you get: you get what you deserve!

This game mod for Arthur Morgan is high-quality, with various skin and hair textures for you to choose from.

Unfortunately, it doesn’t seem like the hair textures can be edited, since I couldn’t find any in sight through OpenIV and decided that they must be embedded in the hair models.
