If my math and understanding of rayleigh scattering is correct, royal blue @ 440nm should scatter 4x as quickly as red @ 620nm and hence be much less visible at long distances. Has anyone noticed this effect in long-distance visibility of light sources?
I can't find any data out there at all -- I may have to set up some emitters in the wilderness and try 1km visibility tests.
