I just think it's highly amusing (in the absurd sense) that you consider a visual artist to be a political ideologue simply for applying color theory to render realistic characters in their art.

#83Seems to underrepresent pale skin tone variety
Under-represent relative to what, exactly?

#84> What colors are we? The short answer is maybe something like “brown” and the long answer is very, very long. Pete Shirley (author of Ray Tracing In One Weekend) is also a part time color scientist, and he clued me into the fact that if you crank the saturation to 100% of pictures of people of any race, the skin color comes out orange. I think I heard that some face detectors may work on this principle, but I don’t…
and brown is just dark orange.
Yes, true! Though cranking saturation doesn’t brighten colors (much… at least it’s not supposed to), and maybe interestingly, light brown isn’t quite orange. There might some asymmetry in color names.
So it might not be that surprising that dark skin people turn orange when sat is cranked, but perhaps slightly surprising that light skin people do.
Anyway, I suspect it’s computationally easier to turn everyone orange than brown. Plus, given that brown skin is already a category, orange could be useful terminology/category.

#85I really like the idea of treating a color space as a task-specific optimization rather than something universal. It makes me wonder if we're underusing domain-specific color spaces in procedural generation in general.

#86I read the “limitations” section’s list of things that affect perceived skin tone and it didn’t mention lighting! This is pretty important as the available light determines the shades that can be perceived.

And orange is just a yellow red.

And brown is just orange... with context.

#89I'm using an iPhone Safari plugin called Noir to force darkmode and your tool is making white the absence of color. In other words, I think white is just an alpha channel.
