Evidence suggests the signal colors were borrowed from the railroads, where red meant “stop,” green meant “caution,” and clear (white) meant “go.” These came into use in the 1830s and 40s. Around 1914, a broken red lens caused a locomotive engineer to mistake this for a clear “go” and smash into an oncoming train with disasterous results (another example of Deadly Design). Subsequently, the red/yellow/green signals we use today were adopted; yellow was thought to provide the greatest contrast to the other two colors.
