    In 1920 Police Officer William Potts addressed the chaotic traffic of Detroit, Michigan, by co-opting the red, amber, and green automatic traffic light system used on railroads. Around the same time, the prolific African American inventor Garrett Morgan devised and patented the precursor to the automatic traffic lights we use today.

    Apparently the colors of red and green were standard in the electrical industry at the time. The makers of railroad signals and traffic lights simply adopted the familiar color scheme.

    Curiously, yellow or amber, is associated with warmth, happiness, and the sun. Despite these connotations, it was chosen to symbolize "caution." Perhaps because it contrasts well with green and red, and is highly visible without being too harsh on the eyes of motorists. Today, yellow is commonly used as a warning symbol for both traffic signs and alert systems.
