Is It Possible to Regulate the Cation System by Light?

The new photoreceptors are maximally sensitive in the blue part of the spectrum - four hundred and eighteen nanometers. Why? Well, it could be because at twilight, the dome of the sky is enriched with blue light. And if you've got receptors tuned to different colors, they can detect ratio changes on those colours which then pass on information for colour vision.
