newbound dark syntax theme for Atom

newbound dark is a subtle, medium contrast theme for Atom, based on the hues and shades from Oliver Pattison’s website. Optimized for writing Markdown and front-end development, it should also work for general use.

  • Medium contrast without any dissonant color pairings
  • Consistent support for syntax grammar across languages
  • Carefully selected, Base16-inspired palette, with blue and red accents
  • Support for UIs that are responsive to hues from syntax themes, like the built-in One Dark UI theme
  • Subtle invisibles (if enabled in Settings)
  • Bracket matching style
  • Suitable for monospace fonts without an italic variant

Specific support for these syntaxes

  • HTML
  • (GitHub-flavored) Markdown
  • Liquid
  • CSS
  • SCSS/Sass
  • Less
  • JavaScript
  • JSON
  • YAML
  • Ruby
  • todo

General support for other languages is intended but not guaranteed.

newbound is friendly toward Jekyll development, particularly if used with liquid-language support (not built-in).

Optimized for One Dark UI and One Light UI.

Use the colors.yml file with Base16 Builder to generate a theme for a different text editor. This theme was created by hand, so results may vary from this implementation.
