Black Light applies visual effects to the screen by changing its gamma curve. You can invert colors, darken the screen beyond what's usually allowed, apply a color filter, or apply the 16-235 luminance gamut expected by some HDTVs.

What's New in Black Light

Version 2.3.5:
  • Resetting gamma curve more proactively on quit, instead of counting on macOS to do it for us. This does not change the behavior of the app but resolves a somewhat nebulous issue with video capture and/or playback with certain applications on particular hardware configurations.

Requirements for Black Light

  • OS X 10.6.6 or later
