There is one thing missing

Change Icon-Theme:

gsettings set org.gnome.desktop.interface icon-theme 'MyIconTheme'

thx a lot for this

Thank you very much

Inspired by this post, I put some commands in a script. But when I run it, not everything turns to light mode. All application windows (e.g. Caja) are still in dark mode. If you have any idea what I am missing, please comment.

gsettings set org.gnome.desktop.interface gtk-theme 'Yaru-light'
flatpak override --user --env=GTK_THEME='Yaru-light'
gsettings set org.cinnamon.theme name 'Mint-Y'
gsettings set org.cinnamon.desktop.interface gtk-theme "Mint-Y"
gsettings set org.cinnamon.desktop.wm.preferences theme "Mint-Y"
gsettings set org.cinnamon.desktop.interface icon-theme 'Mint-Y'
