An Anaglyph is a color method for viewing 3D content without the need for specialized display hardware. In the most common scheme, the weighted luminance of the left eye view of a stereo pair is fed into the red channel of the viewed image, with the green and blue channels retained from the right eye. The viewer wears glasses with a red filter over the left eye and a cyan filter over the right, to ensure the appropriate stereo eye view reaches the appropriate eye.
