Black Light

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.

• Can now toggle the effect individually for each screen.
• If you have more than one screen, can now toggle each screen from the menu behind the the dock menu or from the menu bar.
• Fixed an issue occurring after a restart or a login that would make Black Light inoperative until it was quit and reopened.
