A system for influencing a state of a user includes a display with a light source for emitting light influencing the state of the user. A light controller selectively controls the emission of the light including at least one of； (1) the spectrum of the light； (2) the duration of the light； 3) the distribution of the light； (4) the intensity of the light； and (5) the timing of the light. An analysis engine capable of providing a signal to the light controller indicating a desired emission of the light based upon selectively illuminating one or more of a plurality of different blue light sources, each of which having a different peak spectrum.
