At a Glance: Panda Syntax Dark Theme
Panda is a “superminimal” dark Syntax Theme for a variety of coding IDEs and Terminals created by Siamak Mokhtari. It features a dark background and some lovely subtle colors to make your code look elegant and pleasing to the eyes. The theme is specially crafted for the Atom editor, but you can also download versions for the macOS Terminal.app, iTerm, Sublime Text, and a few other apps.
Unfortunately, there doesn’t appear to be a version for Panic’s Coda yet.
