Iris Night is a fully dark version of the Iris themes, using a bold accent colour with a tinted dark background. It supports Gtk 3.10+ and Gtk 2 (using the Murrine and Pixmap engines).
If you find any bugs, then I'd appreciate it if you could report them on the main Iris Github page with "Iris Night" in the title: github.com/xyl0n/iris
Also see the Iris Dark theme: fav.me/d73sf8i and the Iris Light theme: fav.me/d73dv3h
The icons are Nitrux: fav.me/d4utllr and the shell theme is Elegance Colors: fav.me/d525x6c
Happy tweaking :)
