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
