alt Hacker News> Firstly, maybe I shouldn't have said "saturated," but then again, you wouldn't argue that your earth tones, for example Yellow Ochre or Burnt Sienna aren't saturated in color?
I think you are confusing a definition of saturation meaning "unable to absorb more" with the visual perception definition.
Optical Engineer here, but AFAIK artists use the term the same way: "saturation" refers to how the color is free of both white- and black-shading, "degree of non-grayness" if you will.
The outer ring of this image is fully saturated; you'll see that "muddy" colors like ochre and sienna don't occur there.

The difference here could be because we're in different fields. We would call what you're referring to as "chroma." In historical palettes, almost no colors had that intensity of color at the top of your image. In pigment, a color can be extremely saturated and very dark.
