Abstract
An adaptive anti-glare light system including a sensor, a color selection engine, a controller, and a plurality of light sources each configured to emit a source light. The sensor transmits a source color signal designating a reflected light characterized by a detected color and a discomfort glare rating. The color selection engine determines a dominant wavelength of the detected color, and a combination of the light sources that the controller may operate to emit a combined wavelength that matches the dominant wavelength of the detected color. A method of adapting light as a countermeasure to glare comprises receiving the detected color, determining a subset of the plurality of light sources that may be combined to form an adapted light that matches the detected color, and operating the light sources with a white light to emit the adapted light at or above a threshold discomfort glare level.
