I guess it is all in the eye of the beholder. The python plugin is just my boilerplate file for use with BIMP the GEGL Saturate is simple as far as parameters go. Some of the others more complicated. I find it easier to get the GEGL working in Gimp then apply to the batch-images, or not use GEGL at-all
Um... um... interesting!
I did try colors > hue saturation, colors > saturation, and colors > hue chroma, and strangely, and like you I was not able to get the same saturation, "hue saturation" seems to be very closed to "hue chroma", even though hue-saturation seems to have a bit more "light", but colors > saturation..., is in a different league (if I can say that), all that moving only the saturation slider.
Interesting and learning every day (and quite surprised as well kind of confused
).Thanks a lot Rich for your input.
