A screen inversion tool - switch your colors to Night Mode
Nocturne is a small Mac OS X program which can change your display colors in various ways to give you a color scheme more suited to low light conditions (such as at night).
See the Releases tab on GitHub.
This repo is a collection of all the major contributions found online after the project was open-sourced and the main aim is to give everyone a single place to concentrate efforts.
A special thank goes to BlackTree for creating the app in the first place
