When black & white televisions began to hit the marketplace, the movie theatre industry didn’t see it as a threat being that only a handful could afford the product. In the ‘50s whereas mass production started pumping out volume it was a different story and theatres sought at keeping a step ahead by innovating. One such stroke of genius was the introduction of color movies.
Of course, it didn’t take long for the television camp to follow suit. Four major networks each presented the FCC their version of a color television prototype all different one from the other. Needless to say the FCC was not impressed and quickly sent them packing instructing them to work together on one single standard.
Ironically, the idea of adding colors to black & white TV broadcasts couldn’t be farther from the actual requirements. One engineer dared question and suggest the not so obvious. Why not extract colors from the original black & white and recompose?
Understanding that pure light is composed of all existing colors at their full saturation and the moment light is refracted, by rain droplets for example, a rainbow of color fills the sky. Ever noticed how the colors in a rainbow are always in the same order?
Did you know that the human retina at the back of our eyes is photosensitive to ONLY three (3) colors: red, green & blue? Limitless shades of each three colors multiplied between themselves account for every possible potential natural existing color in the universe.
And that’s exactly how color was introduced to the television broadcasting system, by extracting the blue then the red from the original black & white then recomposing all three versions by superimposing them into one single colorful image.
