Real Pigment is a mod that can make the skin of a PC or NPC look more like how it's meant to be. The way it works is by applying a skin tint to the face and scalp. There are three different options, and you can apply the different tint maps to different characters if you wish.

This mod will apply to all heads (both PC and NPC), so the skin tints will apply to the face and scalp in a way that looks more like how pigment can be distributed in the skin.

There are three options, and they all work in the same way. The first is the base tint map, which is the original skin tint map. The second is the vanilla map, and the third is the patch tint map.

All of them work by applying more tint in the light areas and less in the dark areas.
