GIMP 2.8 and earlier had a useful tool, reached through FX-FOUNDRY -> COLOURS -> GREY POINT. I cannot find anything like it in GIMP 2.10.3, which I have in AppImage form. Nor do I know if the FX-Foundry collection is available for the new version. [I am on Debian 9]

Script attached and working in Gimp 2.10 appimage.
unzip, put rogge-grey-point210.scm in ~/.config/GIMP-AppImage/2.10/scripts/
I got the original from the last set FX scripts for Gimp 2.6 As far as I know no plans to update for Gimp 2.10. They will have to be done an individual basis. Dare say some of them will be impossible to update.
