Man I was just looking to get some info on fog lights, not an education!

The sky appears blue due to a process called Rayleigh scattering. The blue light is absorbed/scattered by particles in the atmosphere, whereas red, yellow, orange pass through directly. This scattering causes it to look blue when you look up towards it. Nothing to do with how 'strong' the blue light, in fact that doesn't really make that much sense to be honest.

As for green being the least sensitive? It is widely known that blue is in fact the least sensitive frequency for the human eye to detect. To see something in blue requires twice as much energy input for a comparative green (or red) source.

For someone called Einstein, I honestly don't know....
