So even when you get the palette right, to paint it like a believable material in a convincing way is still super hard!
Love it! I was looking at this a little while ago, and used some of The Pudding's data on makeup/foundation shades ( https://pudding.cool/2018/06/makeup-shades/ ) and plotted it into the Oklab colorspace ( https://observablehq.com/@55th/foundation-shades ). The shades form themselves into that same crescent as seen in the article.

If you look at my doctoral thesis, in fact skin colour can be parametrised using melanin and haemoglobin concentration; which it means it is indeed (roughly) two dimensional. This allows you to invert the colour of a pixel and identify someone’s chromophore concentration. This is based on previous work of others cited in the thesis. https://discovery.ucl.ac.uk/id/eprint/10093345/
I've heard that the so-called "yellowish" skin color that non-tanned East Asians tend to have, is due to relative abundance of subcutaneous fat. If that's true, is that captured by the haemoglobin dimension or is it a yet another degree of freedom?
People only turn yellow if they have kidney or liver damage. However, some distinctive features like Lucy Liu's natural freckles are tough to draw right.
We looked around a lot for a procedural texture/shader to help make the project characters look less sickly, and please also consider supporting the persons work if you are able:

Best of luck =3
but this is just lovely and inspirational work. A unique marriage of hacking in the celebratory sense, thoughtfulness, and meaningful contribution. Outstanding.

Oh goody, an expert in a question I've always wanted to ask. Once upon a time, I encountered a sort of interactive museum book called "Earthsearch". One of its "exhibits" was a color wheel, made of two spinnable pieces of tinted acetate, that purported to be able to generate any skin tone. I suppose this is three degrees of freedom, since for any position of the two wheels you could access a range of colors around th…

There is a separate effect of increased bilirubin content, that would appear if someone was ill.
Not my domain though I followed the data science enough to nod as if I really followed it, but this is just lovely and inspirational work. A unique marriage of hacking in the celebratory sense, thoughtfulness, and meaningful contribution. Outstanding.
