Abstract
A light source and a method of generating a light using the light source is disclosed. The light source is configured to produce a plurality of distinct colors in generating the light, one of the distinct colors falling within a blue spectral light band. A light controller modulates the spectral light produced by the plurality of distinct colors. The modulation provides melanopsin contrast in order to increase melanopsin responsiveness of a subject exposed to the generated light and maintains the color temperature, color quality, and color constancy experienced by the subject in a lit viewing environment within an acceptable range.
