Calendar Module in Dark Mode

[foersben]

Dear Community,

how can I set the calendar module https://github.com/vivien/i3blocks-contrib/tree/master/calendar into dark mode as shown in the preview?

Thank you in advance!

I personally use lxappareance. You can use a dark theme and calendar module should display into dark mode.

The calendar is using the yad command, which uses your GTK themes as color palettes for the various widgets it provides.
I found this ArchWiki page that describes how to handle GTK themes with this exact section detailing how you can change the configuration files to prefer a dark theme over a light theme.
I ran this command in my shell: gsettings set org.gnome.desktop.interface color-scheme prefer-dark
And added gtk-application-prefer-dark-theme = true to my /usr/share/gtk-3.0/settings.ini, and it changed to dark theme.
I did not try this myself, but if you wouldn't prefer a system wide change, this section details where you can find (or create) the user configuration files.
