forgot about that.
hmm, eyes, perhpahs brown is the most commen, grey an uncommen secondary color, possibly other colors in the main city from traders from other lands mingling into the population. but mostly brown and grey.
and I forgot about the mammoths. deer is likely still more common then mammoth, Because though mammoth hide is more popular, but also much more expensive. (large group hunting together to take down one mammoth, compared to a single hunter bringing in multiple deer).
