I did a few Norman units a few years ago in which I adopted a common colour scheme. Here are the blue and yellows. Probably not historically accurate but who knows? The Bayeux tapestry does not have an opinion. Anyway I thought they looked good and the theme meant that I didn't have to come up with a brand new colour scheme for every figure.
In retrospect their faces do look a bit yellow. I was surprised at this as I do use the GW flesh tones which seem to be pinkier than the VMC ones. But otherwise I was happy with them.
