It's a simple color retexture for Hairworks and originally only intended for the Realbeard mod by rivianbleidd.

It has a lighting mod and a Reshade mod that are used in the first half of the images and is Wiedzmin Lighting Mod by mishikedman and PATHOS Reshade by Pansen1 (without Realbeard and mainly using "Geralt The Ghostly White Beard" file) while the second half is STLMby essenthy and Absolute Prerelease Reshade by mikeywander (mainly with Realbeard and using "Geralt The White Beard" file).

The first half of the images is from the Wiedzmin Lighting Mod by mishikedman and the second half is from STLMby essenthy and Absolute Prerelease Reshade by mikeywander (mainly with Realbeard and using "Geralt The White Beard" file).
