As hinted in my previous image post, here's a Gray Lady skin texture with better detail:
It's based on the bump map textures that were included with the Girl 4 variant of Victoria 4. The conventional wisdom is that you're NOT supposed to make a bump map by desaturating a skin texture to black and white, but that's apparently exactly what they did. Worked out well for my purposes, though. And it has more details-- freckles, etc.-- than the final Girl 4 skintone maps did. Yay!
