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.
- Added vividness slider for the color filter effect. Now you can make the screen slightly yellowish, rosy, etc., by controlling the white point.
- OS X 10.6.6 or later
