A low contrast colour scheme inspired by The Legend of Zelda: Majora's Mask, in particular my memory—or rather—impression of the main area (from which this theme takes its name).
Termina comes in standalone light and dark variants (see further info below).
termina-syntax in Settings > Install > Themes. Or install it directly using the command:
apm install termina-syntax
Project page: https://protesilaos.com/termina
Termina dark version: https://atom.io/themes/termina-dark-syntax
