Though light has a robust stimulatory effect on parasympathetic outflow, it has a dual (inhibitory/stimulatory) effect on sympathetic outflow. Hence the parasympathetic output is controlled by a light-stimulated pathway, Whilst the sympathetic outflow is controlled by separate light-inhibited and light-stimulated pathways. The light-inhibited sympathetic pathway is yoked for the light-stimulated parasympathetic pathway mediating the pupillary light reflex: as the pupil is constricted by stimulation of your parasympathetic pathway, sympathetically mediated pupil dilation is withdrawn (8).

This suggestion has received experimental guidance lately (one hundred and five). It has been shown that blue light has an alerting and green light a sedative effect. Therefore diurnal animals might show a higher sensitivity to blue from the spectrum, and retinal ganglion cells stimulated by blue light might challenge preferentially for the SCN. On the flip side, nocturnal animals' retinae might be extra delicate to green inside the spectrum, and retinal ganglion cells stimulated by green light, might venture preferentially on the VLPO (53, one zero five, 108).
