- ColorCode 3D
-
ColorCode 3D is a newer, patented[1] stereo viewing system deployed in the 2000s that uses amber and blue filters. Notably, unlike other anaglyph systems, ColorCode 3D is intended to provide perceived nearly full colour viewing (particularly within the RG color space) with existing television and paint mediums.

Technology
One eye (left, amber filter) receives the cross-spectrum colour information and one eye (right, blue filter) sees a monochrome image designed to give the depth effect. The human brain ties both images together.
Images viewed without filters will tend to exhibit light-blue and yellow horizontal fringing. The backwards compatible 2D viewing experience for viewers not wearing glasses is improved, generally being better than previous red and green anaglyph imaging systems, and further improved by the use of digital post-processing to minimise fringing. The displayed hues and intensity can be subtly adjusted to further improve the perceived 2D image, with problems only generally found in the case of extreme blue.
The blue filter is centred around 450 nm and the amber filter lets in light at wavelengths at above 500 nm. Wide spectrum colour is possible because the amber filter lets through light across most wavelengths in spectrum. When presented via RGB color model televisions, the original red and green channels from the left image are combined with a monochrome blue channel formed by averaging the right image with the weights {r:0.15,g:0.15,b:0.7}.
Notable Uses
Barack and Michelle Obama, along with their party, watch the commercials during Super Bowl XLIII in the White House theatre using ColorCode 3D.
In the United Kingdom, television station Channel 4 commenced broadcasting a series of programmes encoded using the system during the week of 16 November 2009.[2] Previously the system had been used in the United States for an "all 3-D advertisement" during the 2009 Super Bowl for SoBe, Monsters vs. Aliens animated movie and an advertisement for the Chuck television series in which the full episode the following night used the format.
Viewing Comfort
ColorCode 3D, like most passive stereoscopic 3D technologies, tend to reduce the overall brightness of the viewed image. Also, improperly calibrated displays can cause image ghosting.
