This is covered by Huberman. Our night vision is ~3x more sensitive to blue light than red, probably because starlight has more blue. Blue light is ~2.5 worse for keeping us up but would actually be better if turned it way down like the 3x implies we can. At normal levels the 3x gets lost in the exponential to much light we get at night.
