Color Vision Introduction The eye’s ability to perceive color is determined by the sensitivity of “cones” in the back of the retina which distinguish different wavelengths of light. There are three types of cones: red, green and blue. These three types of cones work by combining the three primary color, much like a video projector. Wavelengths of light in the visible spectrum progress from the shorter violet colors, through the intermediate blue, green and yellow frequencies to the longer orange and red wavelengths. Not all individuals are born with the ability to perceive differences in color for wavelengths of light. Individuals with substandard color vision detection ability are termed color deficient. Men are ten times more susceptible to color vision deficiencies than women are (8% vs.0.8%).

Color Vision Issues in Aviation The aviation environment has some phases which require reliance on the ability to detect differences in color for adequate performance. Some of these environments include night flying with the requirement to distinguish red and green position locating lights on aircraft, LED readouts on the instrumentation and warning lights in the cockpit. Additionally, both day and night flight require the ability to distinguish airport tower beacons and lighting from hazardous towers and other obstructions to flight. In the absence of radio communications, the ability to distinguish colored light gun signals from air traffic control tower is necessary for the safe movement of aircraft around that airport.
