Installing

GTK3 and Gnome-shell

Move theme folders to ~/.themes

GTK4

To install the Gtk4 theme move the contents of gtk4.0 to ~/.config/gtk4.0

Flatpak

To install themes on Flatpak apps use these commands:

sudo flatpak override --filesystem=$HOME/.themes

sudo flatpak override --env=GTK_THEME=MonoTheme

or

sudo flatpak override --env=GTK_THEME=MonoThemeDark

GDM

IMPORTANT❗️ Take a snapshot of the system before use!
If you want the gnome-shell theme to extend to the lock and login screen, move the gnome-shell-theme.gresource file from gnome-shell folder to /usr/share/gnome-shell/ with a replacement and restart system with ALT+F2 and enter r for Xorg or reboot/log out for Wayland session.
Command:

sudo cp gnome-shell-theme.gresource /usr/share/gnome-shell

I recommend saving the gresource file from the folder to a safe place beforehand, if will need to be returned. Go to /usr/share/gnome-shell and open terminal.
Example:

sudo cp gnome-shell-theme.gresource ~/Documents

Firefox

Install Firefox Theme

Using

The dark and light appearance of Gtk4 is changed by renaming the desired file to gtk.css in .config/gtk4.0. At the moment there is no or I haven't found another way to change the color.
To change the light or dark theme of Gtk3 apps and Gnome-shell use Gnome Tweaks or Night Theme Switcher (choose the MonoTheme for day and MonoThemeDark for night variant in the Themes tab and change the theme color by switching style in Settings > Appearance).
