Materia is a Material Design theme for GNOME/GTK based desktop environments.

It supports GTK 2, GTK 3, GTK 4, GNOME Shell, Budgie, Cinnamon, MATE, Unity, Xfce, LightDM, GDM, Chrome theme, etc.

Supports ripple animations for GTK 3 and 4:

3 color variants and 2 size variants are available:

Materia	standard	compact
standard
dark
light

• GTK 2
• GTK 3 >=3.20
• GTK 4 >=4.0
• Budgie >=10.4
• Cinnamon >=3.x
• GNOME Shell >=3.26
• MATE >=1.14
• Unity >=7.4
• Xfce >=4.13

• elementary apps

  Because they are based on their own stylesheet that conflicts with GTK standards.

• Downstream customized GNOME sessions

  E.g. "Ubuntu" session, "Pop" session. To properly use Materia on GNOME Shell, please install gnome-session and then switch to "GNOME" or "GNOME on Xorg" session from your display manager.

NOTE: Distro packages could be outdated and incompatible with your desktop environment. You can check the latest version here.

All 6 variants are available via Flathub:

flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak install flathub org.gtk.Gtk3theme.Materia{,-dark,-light}{,-compact}

See INSTALL.md for details.

• Use a font family including Medium weight (e.g. Roboto or M+) to properly display the theme.
• Set the font size to 9.75 (= 13px at 96dpi) or 10.5 (= 14px at 96dpi).

To improve the appearance of Chrome, you can install our Chrome extensions as follows:

1. Open the /usr/share/themes/Materia<-variant>/chrome folder in your file manager.
2. Drag and drop the .crx files into the Chrome's Extensions page (chrome://extensions).

You can change the GDM (lock/login screen) theme by replacing the default GNOME Shell theme.
See INSTALL_GDM_THEME.md for details.

Materia can be customized with GUI application, oomox theme designer.

Materia also allows you to change the color scheme relatively easily in other ways. See HACKING.md for details.

If you find bugs or have suggestions, please report it to the issue tracker. Any contribution would be much appreciated.
