Nocturne

Sometimes you should be afraid of the light…

Nocturne is a simple app for switching a computer to night vision mode. It does, however, add a few things:

• Color correction in inverted and monochrome modes - you can correct hues when inverted and won't lose a channel when using tinted monochrome.
• Window shadow toggling - if glowing windows aren't your thing.
• Background removal - hide the desktop picture so you don't see an inverted version.

After you launch Nocturne, an icon will appear in your menu bar showing a tiny black sun with a white crescent moon inside it. Click here for the drop-down menu to turn Nocturne on and off. If you don't notice this little feature, you may not be able to figure out how to turn Nocturne off once you start it!
