Here’s an alternate version of my Egyptian archer that gives him a coat of reddish otjize paste made from red ochre, ash, and rancid butter. I got this idea from the Himba people of Namibia, who smear themselves with this paste as protection against the desert climate. Since the Egyptians also lived in a desert environment, maybe they would have a similar practice. It certainly could explain the reddish coloring of Egyptian characters, particularly men, in their artwork.
Unfortunately I wasn’t sure how to make the otjize covering look like an actual paste in Photoshop, so instead you get a guy who looks unrealistically red-skinned.
