蛍 Syntax Theme
Hotaru (firefly) is a dark theme that, like my other themes, is based off a keycap set called GMK Firefly.
This theme is mainly optimized for JS but looks great (in my opinion) with other languages.
On your console:
apm install hotaru-syntax
or install via Atom's settings install tab.
Works great when paired with a dynamic UI theme like Kecleon UI.
apm install kecleon-ui
