DuoTone Nature
A double-hue dark syntax theme for Atom based on duotone-syntax.
DuoTone themes use only 2 hues (8 shades in total). It tones down less important parts (like punctuation and brackets) and highlights only the important ones. This leads to a more calm color scheme, but still lets you find the stuff you're looking for.
Language support
DuoTone themes are optimized for many languages:
C, Clojure, CoffeeScript, C#, CSS, GF Markdown, Go, Haskell, HTML, Java, JavaScript, JSON, Less, Perl, PHP, Python, Ruby, SASS, SCSS, Stylus, XML, YAML...
