Blue light is generally bad circadian rhythms (animals and humans):

Another study on crime and streetlights:

> A 2015 study published in the Journal of Epidemiology and Community Health found that streetlights don’t prevent accidents or crime, but do cost a lot of money. The researchers looked at data on road traffic collisions and crime in 62 local authorities in England and Wales and found that lighting had no effect, whether authorities had turned them off completely, dimmed them, turned them off at certain hours, or substituted low-power LED lamps.

So that 2015 study looks at light versus less light, but the claim I've seen circulated quite often is that the color of the light makes a difference. It seems dubious and has little backing information... and I guess my question is why it's become such a popular theory.
