Hi, I have a human model that I extracted from an online source.  When extracted, it comes through with separate head and body textures.  This particular character should have black or dark brown hair, shown at #1 in this attached photo.  The hair portions of this texture aren't colored right; #2 shows the bulk of the hair, and #3 shows the wispy hair strands that should give it some good detail.  Instead of dark brown or black, the hair is coming through as blue/green/grey, and the strands are showing as yellow.  This is something that the in-game engine from which this model originated has some kind of procedure to display properly.  I haven't been able to replicate that, so now I'm just trying to figure out how to modify the colors of the multi-colored blob so that they align with his intended hair color.  I'm guessing I'm going to need to paint over it in some way, but I'm open to any suggestions.

By the way, this is the original texture file, with layers, in case that provides better information:
