@ MikeMiTichi: I gave it 2 more shades for skin, so I didn't overlook your previous comment.
Alright, I'm confused at how to do this. Right now I have 8 shades of black, 6 skin shades, the background color, and the eye shade. Admittedly, the eye shade is only used for one pixel, so I could probably do away with that to make room for other shades, but I am uncertain exactly what I should be changing. I don't know what to get rid of in the blacks, and I honestly don't think I understand just where it is that the skin is a problem.
If you could give me a visual example (i.e. circle the problem zones or something to that effect) it would help, because I have a poor eye for detail. ^_^
