There's something else I'm kind of stuck on... introducing Sisko. I can't figure out how to colorize white skin to brown. I assume that there must be a reasonable way to do it. First, I tried taking a copy of the hands, perform a desaturation, then try to introduce a brownish tone. I couldn't get Photoshop to give me brown tones. I also tried simple hue shifts and darkening... wouldn't work. I then thought about trying a color matching from his facial skin tones, but that seems way too tedious. Any ideas?
