Black Light allow you to invert the colors on your screen. This is done by inverting the gamma curve of the screen. When you open Black Light, the screen is automaticly inverted. Colors are restored when you quit. You can click on Black Light’s icon in the Dock to toggle between the two states.
From the preferences you can also activate some special effects. It is possible to, beside inverting the screen, dim the screen or hide stripes of the Aqua interface (by removing all light grays). Black Light 1.6 also feature a color filter mode so you can make the screen black and red, or green, if you want.
