While Technicolor eventually became the industry standard, it was not the first color process. That title belongs to 'Kinemacolor,' invented by George Albert Smith in 1906 and first commercially exhibited in 1908. Kinemacolor used a black-and-white film projected through rotating red and green filters. While it looked surprisingly realistic for the time, it had major flaws: it required twice the amount of film and a special projector that frequently broke down. It also couldn't reproduce the color blue (which appeared as shades of green or gray). Hollywood studios eventually passed on Kinemacolor in favor of Technicolor's more stable three-strip process, which could capture the full spectrum of color and didn't require theaters to buy expensive new projection equipment.
