Solarized Minimal Dark for Atom
Solarized Minimal is a syntax theme using the Solarized palette by Ethan Schoonover. One of the unique features of Solarized is that it supports both a dark and light theme, using the same sixteen colors.
Atom supports syntax highlighting based on the format and grammar used in TextMate. This makes it possible to theme pretty much any part of a document, but that doesn't necessarily mean you should.
Solarized Minimal attempts to create a more homogeneous and subtle use of the Solarized palette by assigning colors primarily through the root groups described in the TextMate documentation.
