How to change the theme of one application in elementary os?

Question

linux

I put a dark theme on elementary with the help of tweaks. All apps look great except for the ill-fated clipboard from the app store. Is it possible somehow to force him to turn on the light theme, under which he was written?

Answer 1

run the application after declaring a theme variable
or write something like this in the *.desktop file
:
Exec=env GTK_THEME=Adwaita:
dark geany

Answer 2

Look in the application settings, although if the OS theme changes for all applications automatically, then rather, you may need to return the old theme.
