Zenburn is a low contrast color scheme that was originally created for Vim and then applied to many popular editors and environments. According to the author "it's easy for your eyes and designed to keep you in the zone for long programming sessions."
Tomorrow theme is a bright color theme that aids your programming "with easily identifiable colours that add meaning and enhance legibility" with several theme variations (Tomorrow, TomorrowNight, TomorrowNightBright, TomorrowNightBlue, and TomorrowNightEighties).
ZeroBrane Studio always allowed for configuring colors used in the IDE, but it was not consistently applied to some of the areas in the Output/Console windows and some elements were not available for styling at all (like markers and their background). Now you can switch between color schemes (using
cfg/scheme-picker.lua script) and see the immediate effect of your changes; you still need to update the
cfg/user.lua configuration file after you settle on a particular scheme.
Here is the screenshot of an editor tab with Zenburn color scheme applied:
The number of colors used is set to 12 to provide some consistency across different color schemes; you can extend them to get more variety if you want. The current version of ZeroBrane Studio (get the most recent one from Github until v0.34 is out) supports Zenburn (thanks to Srdjan Marković for mapping Zenburn colors to the ZBS format) and six Tomorrow theme variations in addition to the default color scheme. Thanks to Christoph Kubisch for putting the original styling mechanism in place.
