AUR helpers are not officialy supported, so you can also install it manually from either rolling-release or stable PKGBUILD.

oomox-gui

Oomox can be installed by using a third party COPR repository:

sudo dnf copr enable tcg/themes
sudo dnf install oomox

For Debian 9+, Ubuntu 17.04+ or Linux Mint 19+ you can download oomox.deb package here: https://github.com/themix-project/oomox/releases Make sure what universe repository is enabled.

sudo dpkg -i ./oomox_VERSION_17.04+.deb  # or ./oomox_VERSION_18.10+.deb for Ubuntu 18.10+
sudo apt install -f

Or, if you don't want to install third-party binary package you can build it on your own:

# with docker:
sudo systemctl start docker
sudo ./packaging/ubuntu/docker_ubuntu_package.sh  # sudo is not needed if your user is in docker group

# or directly from ubuntu host if you don't like docker:
./packaging/ubuntu/create_ubuntu_package.sh control
# or ./packaging/ubuntu/create_ubuntu_package.sh control_1810

./gui.sh

After exporting a theme select the generated theme (oomox-YOUR-THEME-NAME) in your appearance config tool (for example, lxappearance or gnome-tweak-tool).

If your prefer CLI interface, refer to change_color.sh scripts inside ./plugins/. For xresources and random themes in CLI use palettes from /opt/oomox/scripted_colors/ directory. Using scripted palettes enables you to use bash to write simple generators for dynamic themes (as alternative to plugins in oomox-gui). GUI is not attempting to execute any scripted palettes with bash because downloading such scripted themes from random places could lead to unexpected result so you can use them only with CLI, when you really know what you're doing.

Spotify theme can be also exported from GUI, but if you prefer commandline interface:

./plugins/oomoxify/oomoxify.sh ./colors/gnome-colors/shiki-noble

Also you can normalize font weight with -w argument, see -h for usage.

Spotify theme settings are backed up to ~/.config/oomox/spotify_backup. To undo the changes made by oomoxify, these files can be copied back to their original location /usr/share/spotify/Apps. Spotify can also be reinstalled, which will reset these files as well.

Users running Spotify under Flatpak should set their "Spotify path" in oomox to /var/lib/flatpak/app/com.spotify.Client/current/active/files/extra/share/spotify/Apps in order to apply the theme.

Create/append to ~/.config/gtk-3.0/gtk.css:

// remove window title from Client-Side Decorations
.solid-csd headerbar .title {
    font-size: 0;
}
