Since I wanted to have a mixture of skin tones for my Askari, I kept some notes for my future painting endeavours. Maybe these could be put into the first post by Hammers should this become a sticky? Should that be the case, I'll remove the info from this post. I've added pictures for the forum where I had examples. More could be added.
Did I miss someone?
