Here are 11 Face Painting styles. Since they all use the same file, you can only use one of them in the game.
I've noticed that, when creating your character, darker skin color will also make the paint darker.
NPC's and summons may use the same texture as your character .



Instalation:
Install DSfix and enableTextureOverride 1 in your dsfix.ini
and copy one beard style to:
...\Dark Souls Prepare to Die Edition\DATA\dsfix\tex_override
