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.

And orange is just a yellow red.
