Race recoloring its my hack
Right now is done only based on race. Its compute new colors and after that it's search for some pixel color groups in sprite. If it find proper pixel it replace with new one.
Every thing is hardcoded and can't be change (only turn off).
I made patch that relaxes it a bit (this is require by TFTD, not jet included to OXC) and colors can be changes freely for any combinations of gender and race, but you would need sacrifice change of hair or face color to archive your effect.
If my patch pass, I could add in my extended version option for third color to replace, that would allow you to archive your needs.
