Chromadepth is a patented system from the company Chromatek that produces a stereoscopic effect based upon differences in the diffraction of color through a special prism-like holographic film fitted into glasses. A patent is a set of Exclusive rights granted by a State to an inventor or his assignee for a fixed period of time in exchange for a disclosure of an Stereoscopy, stereoscopic imaging or 3-D (three-dimensional imaging is any technique capable of recording three-dimensional visual Diffraction is normally taken to refer to various phenomena which occur when a wave encounters an obstacle In Optics, a prism is a transparent optical element with flat polished surfaces that refract Light. Holography (from the Greek, ὅλος - hólos whole + γραφή - grafē writing drawing is a technique that allows the Glasses, also called eyeglasses or spectacles, are frames bearing lenses worn in front of the Eyes normally for vision correction, Chromadepth glasses give the illusion of colors taking up different positions in space, with red being in front, and blue being in back. Any media piece can be given a 3D effect as long as the color spectrum is put into use with the foreground being in red, and the background in blue. Three-dimensional space is a geometric model of the physical Universe in which we live From front to back the scheme follows the visible light spectrum, from red to orange, yellow, green and blue. The electromagnetic (EM spectrum is the range of all possible Electromagnetic radiation frequencies
The system was used variously for comic-books, educational books for children, light show displays at such planetariums as the Hayden Planetarium in New York City, and other printed and projected applications. This method was also used for I Love the '80s 3-D and glasses could be bought at Best Buy. I Love the '80s 3-D is the follow-up to VH1 's 1980s nostalgia show I Love the '80s and its sequel I Love the '80s Strikes Best Buy Co Inc ( is a Fortune 100 company and the largest specialty retailer of Consumer electronics in the United States and Canada Chromadepth has recently been put into use in Crayola's 3D Chalk. Crayola is a brand of marking utensils such as markers chalk crayons and colored pencils manufactured by Crayola LLC (formerly Binney & Smith This technique was also used by the production company Quirky Motion for the music video promoting New Cassettes 2007 single "recover/retreat" as part of the BBC Electric Proms [1]
