Solarized Dark
These color schemes are for PHPStorm 2.x. They are (to my knowledge) complete for every language PHPStorm supports.
The original documentation about the Solarized color schemes can be found here: http://ethanschoonover.com/solarized
I recommend using the font "Inconsolata" with this color scheme.
