No other steps, except re-starting Gimp. Works as shown in the video.

Edit: Checked again in Windows and can not find problem.
You did unzip it ?  When editing careful not to introduce any spaces scale=0.5 is correct  scale  = 0.5 is not

I did not edit your file, just put it in C:\Users\kidderj\AppData\Roaming\GIMP\2.10\plug-ins

I don't get why I don't see it in the menu?

I did unzip it and opened it in Notepad ++ but still no menu item.

I was able to get it to work by uninstalling and reinstalling the same version of GIMP 2.10.24, no changes to the .py file.  Thanks for all your help!

Tried again today with a more "serious" gradient-chart and white writing on black BG
A neutral for you, if you want to try
   

Color>Saturation quickly bleed out on the white writing especially in the cyan and green (scale up to 2), but all colors will bleed on the white when pushed hardly (scale ➤ 2)

Color> Hue Saturation seems to be a proper one as at equivalent saturation (full throttle in the Hue-Saturation window) cyan and green are not bleeding out

When I said a proper one -> it seems to be... but rich2005 got the point when he says "I guess it is all in the eye of the beholder"

New day, modified plugin with 1.2 as the GEGL Saturation value. There is no 1200, the scale goes from 0.0  to 10.0

Included in the zip is a simple text editor if (when) you need to modify the scale value. It is not difficult.

This a video demo, from unpacking the zip through to applying BIMP.  https://youtu.be/JNlbuYJlHEQ

Quote:Or if there is an easier way, like doing a batch command that would utilize the saturation level of an existing file.

I do not think so, there is a way with the g'mic plugin of comparing a before / after pair, extracting a color-look-up-table (CLUT) and applying that to other images. Not sure you can apply that particular gmic filter with BIMP.
Another way is, adjust an image with the color-curve tool and save the curve settings as a file. BIMP will apply that color-curve using the file.

@PixLab
nice screenshots, pays to read the first post as the OP specifically does not want to use hue-saturation.

Hey, just wanted to say thanks for writing this plugin up!

The GIMP manual has a link to this page explaining why there is a difference: https://ninedegreesbelow.com/photography...hroma.html
