Note: Melanopsin is the name of the ipRGC's photopigments.

I've seems studies showing that genetically modified blind mices with ipRGC had circadian cycle. And that just a few photons of blue light is capable of suppress melatonin production in humans.
But I haven't seem anything about supression of melatonin being regulated by the ratio of yellow light and blue light. Could you provide a source?
