Oh dear…there are pathways in the human brain activated by light frequency, it’s an entire area of research known as optogenetics.
Similarly, some disorders of sleep can be treated with chromotherapy, goggles of intense colored light.

Lol! Wut? Is this person stupid? Since when is the color of the light, the problem? It’s the fact that you scroll when you should be winding down for the night, and then keep scrolling well past the point when you should be sleeping.

They explain where the confusion comes from in the first two paragraphs.
Different wavelengths of light do affect some biological processes, and circadian rhythms are affected by light. From what I understand, there is some consensus that the brightness of the light source can affect sleep. There is no consensus on whether some wavelengths of light are better than others, but it was a reasonable thing to explore.
