[Description]

Yesterday I was trying to get my character to have black lipstick, however the closest I could get was dark brown and that bugged me a lot, I tried different make up mods and what not but the color was still the same, I've spend a lot of time searching for an answer but couldn't really find any, only something about using custom races with custom textures. Inspecting the matter I figured out (I could be wrong) that the color affected by the lips' diffuse color from the texture, so I decided to brute force my way through that.

I darkened the lips are in the diffuse texture to get the colors darker.
The texture is based on the The Pure CBBE and UNP - 4K or 8K Female Skin Textures made by Anini and Regenbot03 and Shiva182, although the texture will work on it's own I will label the mod required.

I also recommend using this with custom race because otherwise it will affect all NCPs as well. 
Anyway I'm just uploading it here so I don't lose it in the future, there probably are more effective ways of solving this but I really don't want to bother with complicated stuff.
I also recommend it's use with some make-up mod that adds lipstick overlays (difference is shown in the pictures)
