This international standard specifies the light contrast of two lights of different colors, taking into account the age-related change in the luminous spectral efficiency of the eye.

This International Standard provides a basic calculation method that can be applied to the design of lighting, visual signs and displays. It applies to light, self-luminous or reflected, in visual signals and displays viewed under conditions of moderate brightness, called photopic vision and whose spectral radiation is known or measurable. This does not apply to light seen in darker conditions called mesopic or scotopic vision.

Geographic scope of application: International
