Base2Tone
Based on DuoTone themes by Simurai for Atom.
“DuoTone themes use only 2 hues (7 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.”
Base2Tone has it’s own dedicated repository, and demopage on http://base2t.one.
