SE version here

This will add FaceTints with no makeup for all humanoid vanilla NPCs. Children and beasts are not included. You can have loose files or a bsa version with an ESP.
The normal FaceTints are in normal Skyrim format 256 since it's only skintone, but the warpaint ones are in 1024, both formats are compressed with added mipmaps.

For the BSA version you'll need all DLCs but with the loose version it's a fomod so choose what you want.

I've also added the edited tintmasks, so you can make your own FaceTints for other mods that are not covered by this one. If you have the SKSE.ini, then you have to change tint resolution to 256, otherwise the Creation Kit won't be able to make a FaceTint.

Install
Install with a mod manager (Recommended)
Take the content of the folders and paste it in your data folder

Uninstall
Uninstall with a mod manager (Recommended)

BSA version: Delete the esp and the bsa
Loose version: Go to textures\actors\character\facegendata\facetint and delete Skyrim.esm, Dawnguard.esm, Dragonborn.esm and Hearthfires.esm
If using NMM, you may have to reinstall all mods that use loose textures and edits vanilla NPCs.

Compatibility
You might not want to overwrite FaceTints from another NPC overhaul in case they change skintone which will create a neckseam. However, if they don't change skintone, then go ahead.
