This mod will make Yennefers hair a darker shade of black when using Yen Curly Hair Mod instead of the grey or faded black hair color with the original mod.

This is the mod which im retexturing a darker black hair look for.

V2.5 makes her hair around 15-20% darker then 1.0 and finally all shades of grey are gone. Also added longer distance to the lod files.
mod0CurlyDarkBlackHairYenv1 has maybe some grey left in it 10% at most
mod0CurlyDarkBlackHairYenv2 should have all grey shades gone with darker shade of black
mod0CurlyDarkBlackHairYenv3 all grey gone with darkest shade of black

This is for version 1.0 info:
I did 3 different versions of the file with different shades of black.

V1 folder is the darkest shade of black out of the 3 folders.

V2 folder is slightly lighter black. This is the file i recommend to try first.

V3 folder is the lightest shade of black but still gives Yen black hair compared to not using this mod at all.

I took NMM download button off for a reason. It probably wont install right with 3 different folders. Also if you havent figured out how to install mods manually by now you're in trouble. Not to mention NMM causes alot of bugs.  Only pick 1 folder and install it into Witcher3/mods/.
