Lack of Color Saturation in Shadows ...
2

... often gets mentioned here, usually disparagingly.

There is a fix in CIELAB space, at least in RawTherapee:

"CL Curve

The CL curve (chromaticity [i.e. saturation], according to lightness) allows to control the output chromaticity based on the input lightness, C=f(L). It allows you to separately control the chromaticity of regions of the image based on their lightness, so you can for example decrease the chromaticity of shadows if they are noisy or for artistic purposes, or increase the chromaticity of dark and mid-tones without affecting the bright sky."

Of course, if Sigma/Foveon has decreased the chromaticity of shadows because they are noisy **, then I suppose one would get some noise back ...

... personally, I don't mind shadows lacking chromaticity but it does seem to bother some folks.

** chroma noise, that is.
