I hope someone else will respond, because I seem to remember someone having hair and skin palettes. This might give you a start for skin (it only has the number references, though): http://www.sanctuary4u.com/~carinsharon/tutorial/skin_tones.html The other thing you might do is take a graphic and sample the different skin areas using Photoshop or Paint Shop Pro or an equivalent program. This is for a cartoon, but it does give some idea of color ranges for different shades of skin: http://elfwood.lysator.liu.se/farp/flesh/fleshtone3.html I'm sure someone here will come up with a better references.
