Arc Deep Dark is a flat theme with transparent elements for GTK 3 and Gnome-Shell which supports GTK 3 based desktop environments like Gnome.

For me a deep dark color is more elegant and aesthetic, can be a perfect complement to the type comfy desktops. For some it may not seem like a big change but it makes the difference.

• Gnome/GTK 3.14, 3.16, 3.18, 3.20 or 3.22
