DONE
Emacs colors not updating with theme
troubleshooting

Behaviour
Emacs's text and background background is fixed to black on white even when setting the theme to just modus-vivendi (see "dark-mode" images).
Environment
[ GNOME ] & Wayland.
Notes

(set-background-color "blue") does update the background color.

Fix
run (customize-face 'default) and make sure that background and foreground are not fixed 🤦.
