How could I add Gimp 2.8's UI theme to Gimp 2.10?
I'm using the deb-installed variant of Gimp 2.10.18 on stock Ubuntu 20.04 with Gnome 3 desktop.
Gimp 2.10 offers majorly revamped themes (There are now Dark, Grey, Light, and System). I struggle to find them either useful or usable. I can't perceive the end-result in these new themes, so I can't know where I stand with editing until I export and open the image in its final target context (where I want to present it).
This slows me down immensely. Yesterday I edited 3 landscape photos throughout 10 hours! I also have doubts that I could reach the best possible results throughout all this struggling.
Could I add Gimp 2.8's familiar, proven-to-be-productive default theme to Gimp 2.10?
(Note: I have already found and use the Legacy icon theme, which is nice. The challenge that I'm facing is with the background color of windows and various graphs.)

Gimp themes are defined in /usr/share/gimp/2.0/themes/${ThemeName}/.
The most important part of the theme is the gtkrc file.
There are very few differences between the 2.08 Default and the 2.10 System themes (none of these defines any color).
If your problem is mostly a matter of colors, you can copy any of the non-System themes and edit the gtkrc file to define your own colors (some strategic colors are defined at the top).
