Nordish is loosely based on Nord, the color scheme I am using everywhere else. It features muted, arctic, and late-fall, early-winter, colors. I have found that, for my needs, this is the most calming theme I can use. It’s not for everyone, though, but I like it.
To install click the button below on your device. It should open Pythonista 3 and install the theme. It can then be selected from the list.
