That is why the forehead got so dark when using the white hair color. What that file does is change the eyebrow and forehead color.

It is the HUM_270_Face_, and HUF_270_Face_ files.

I am not sure how I can fix this entirely, but I know what file is the culprit. I have corrected it so it's not nearly as noticable, but it is still there. I apparently didn't use UI Goku's forehead files and that caused the highly noticable bug. I figured out what was wrong with the forehead color bug. I also added in all of the vanilla hair styles that came with the game so y'all can change the hair from Goku's to whatever you want, but don't forget there are hair mods on this site for use as well. I updated the mod to include an all race version and it should work just like the original.
