A dark tint2 panel theme for window managers that don't provide one. The menu uses jgmenu, so endeavour to install it (you can change to another menu of your choice anyway).
Simply copy the downloaded tint2rc file to ~/.config/tint2 folder.
Open up tint2 panel manager and select Alien-Black.
Click on "make default" to set it as your default theme or add the following to your autostart script (tint2 -c ~/.config/tint2/Alien-Black.tint2rc)
