Tell specific apps to use dark theme

[Niisse]

Hi peeps, first post here.

I'm looking for a way to force an application to use the dark variant of a theme on startup.Is this possible, for example by setting an environment variable? I have been looking around for a bit but I can't seem to find anything about it. Any help is greatly appreciated!

Some apps have this option "prefer variant", many Gnome apps like gnome-terminal:

I'm not sure, there might be some GTK setting or variable that controls this. But still, there are many apps which don't have this option or don't respect the setting.

Thank you for your reply. I'm aware of some apps having those settings. However, the ones I'd like to change are the ones that don't have such a setting

Specifically, I'd like dark-themed Electron apps such as Spotify and Discord to have a dark titlebar.

I'm not sure, there might be some GTK setting or variable that controls this. But still, there are many apps which don't have this option or don't respect the setting.

I have tried to use the environment variable

Code: Select all

GTK_THEME=Mint-Y-Dark-Aqua

and while this does theme GTK apps accordingly, the titlebar remains light.

This works for me:

Code: Select all

GTK_CSD=1 GTK_THEME=Mint-Y-Dark-Aqua:dark xfce4-terminal --disable-server

Thank you. That does work for something like Xed, but it doesn't seem to affect Spotify or Discord. Still, a step in the right direction
