Here you go! I tried to get what it actually looks like in person, but I wasn't that successful, except in a couple of grainy shots. ^^;;
The first 2 are 'natural light' and are most what the head looks like on the body.
The third picture has 'flash' and makes the head look REALLY different than the body but in person, it's not that bad of a match.
I put a normal skin head on his right and a GUY skin head on his left.
I don't need this "C" head any longer (since the rooter took so long to finish it, I ended up having to reroot a different head for the doll I was making and this now became 'extra.') so if you want it, send me a PM and I'll come up with a price. Probably around $12-15 USD or so.
Anyway, it's easy to paint match the head (I've done it dozens of times) and it's also quite easy to blush the head to make it appear darker. (Also done that many times.)
For the paint method, you'll need acrylic paint, and either water or paint thinner to make it REALLY REALLY thin (consistency of half and half). Then using a soft bristle brush, paint the head with even strokes. You may need two coats (probably) but make sure they're always very very thin so there's no 'brush' marks or globs. After it's all dry, I varnish it with a MATTE sealant---particularly Liquitex MATTE brush on.
I used to use spray sealant on the 1/6, too, but Volks heads are REALLY rubbery/vinyl (moreso than Obitsu) and they'll eventually become super sticky after a few years if you use a spray type like the Volks Zoukei Mura Powder Finishing Spray. Not sure about MSC as I've never used it on the 1/6 Volks heads after all the other major hobby types of 'spray varnish' got tacky on these heads and I was afraid to try it.... ^^;;
I also recommend painting the head 'tan' AFTER your hair/hairstyle is in because you won't really be able to hot water perm the head once you 'paint' it.
Some samples where I've done that method are here:
The Blush method is easier and just requires good pastels like Volks ZM pastels that spread evenly. This works well but is more subtle. You can blush a little or a lot depending on how close a match to your body you want. This is an example of a slight blushing:
