Could you tell me how you got different the hair colors?
In the module_skins, at the end of every face texture theres hex code, the hex code dictates the range of hair colors for that face, so you can get the hex color code for pink and paste it after the 0xFF replacing the existing one at the end and the range of the color will go to pink.
Think of the 4 hex colors after the faces
|Light color | still a light color | darker color | dark color|
So replace one of the hex codes at the front of or end with a large color change and you'll get that.
