So, I figure you know this but if you don't, the Humanae project used to have an official Tumblr blog that went down a while ago, with a ton of photos that aren't available on the current official webpage. I found a Github repo that had recovered and archived links to 9000+ of the images on that blog (apparently they're still hanging out on Tumblr's servers), but a giant pile of links is not very easy to traverse.
I threw together some code that ran through all the images, grabbed the background colors from all of them, and compiled them into palettes. You can look at and download them here. :)
They're divided into "light", "medium", and "dark" palettes based on the HSV lightness values of the colors - swatches in the top third of the range are "light", middle third are "medium", bottom third are "dark". It is basically arbitrary, I just split them up because I thought they would be easier to use that way.
The data set is pretty biased towards lighter skin tones, which is disappointing but not totally surprising, since the webpage for Humanae suggests most of the cities visited were in white-majority countries. Still, I hope it's useful to someone! Palettes of actual human skintones.
Thank you for sharing, nonetheless!
