One Dark UI theme Build Status

This package is now a part of the core Atom repository, please direct all issues and pull requests there in the future!

A dark UI theme that adapts to most syntax themes.

One dark UI

The font used in the screenshot is Fira Mono.


This theme comes bundled with Atom and can be activated by going to the Settings > Themes section and selecting "One Dark" from the UI Themes drop-down menu.


In the theme settings you can:

  • Change the Font Size to scale the whole UI up or down.
  • Choose between 3 Tab Sizing modes.
  • Hide the dock buttons.

To make changes, go to Settings > Themes > One Dark UI > Settings or the cog icon next to the theme picker.


It's also possible to resize only certain areas by adding the following to your styles.less (Use DevTools to find the right selectors):

.theme-one-dark-ui {
  .tab-bar { font-size: 18px; }
  .tree-view { font-size: 14px; }
  .status-bar { font-size: 12px; }


Why do the colors change when I switch Syntax themes? This UI theme uses the same background color as the chosen syntax theme. If that syntax theme has a light background color, it only uses its hue, but otherwise stays dark. This lets you use dark-light combos.
