A flat dark color scheme based off the base16-tomorrow dark color palette.

Set your Sidebar Theme to this, under Preferences:
#282A2E,#282A2E,#373B41,#F0C674,#373B41,#E0E0E0,#B5BD68,#CC6666

Thanks to Chris Kempson for the base16 color palettes (http://chriskempson.github.io/base16/).

Big thanks to lacour, Jonathan la Cour, for creating the original Slack Night Mode, Slack Night Mode, off which this is functionally based (just the colors and typeface changed).
