Color television is part of the history of television, the technology of television and practices associated with television's transmission of moving images in color video.

In its most basic form, a color broadcast can be created by broadcasting three monochrome images, one each in the three colors of red, green and blue (RGB). When displayed together or in rapid succession, these images will blend together to produce a full color image as seen by the viewer.

One of the great technical challenges of introducing color broadcast television was the desire to conserve bandwidth, potentially three times that of the existing black-and-white (B&W) standards, and not use an excessive amount of radio spectrum. In the United States, after considerable research, the National Television Systems Committee approved an all-electronic system developed by RCA which encoded the color information separately from the brightness information and greatly reduced the resolution of the color information in order to conserve bandwidth. The brightness image remained compatible with existing B&W television sets at slightly reduced resolution, while color televisions could decode the extra information in the signal and produce a limited-resolution color display. The higher resolution B&W and lower resolution color images combine in the eye to produce a seemingly high-resolution color image. The NTSC standard represented a major technical achievement.

Sir Isaac Newton PRS MP (25 December 1642 – 20 March 1727 [NS: 4 January 1643 – 31 March 1727]) was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian, who has been "considered by many to be the greatest and most influential scientist who ever lived." His monograph Philosophiæ Naturalis Principia Mathematica, published in 1687, lays the foundations for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion, which dominated the scientific view of the physical universe for the next three centuries. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws, by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the Scientific Revolution.

Joel David Coen (born November 29, 1954) and Ethan Jesse Coen (born September 21, 1957) known together professionally as the Coen brothers, are American filmmakers. Their films include Blood Simple, Fargo, The Big Lebowski, O Brother, Where Art Thou?, No Country for Old Men, and True Grit.

The brothers write, direct and produce their films jointly, although until recently Joel received sole credit for directing and Ethan for producing. They often alternate top billing for their screenplays while sharing film credits for editor under the alias Roderick Jaynes.

Joel and Ethan Coen, of Jewish heritage, grew up in a Jewish community in St. Louis Park, Minnesota, a suburb of Minneapolis. Their father, Edward, was an economist at the University of Minnesota, and their mother, Rena, an art historian at St. Cloud State University.

When they were children, Joel saved money from mowing lawns to buy a Vivitar Super 8 camera. Together, the brothers remade movies they saw on television with a neighborhood kid, Mark Zimering ("Zeimers"),^{[citation needed]} as the star. Their first attempt was a romp titled, Henry Kissinger, Man on the Go. Cornel Wilde's The Naked Prey (1966) became their Zeimers in Zambia, which also featured Ethan as a native with a spear.
