Yellow Colour Lighting during fog

We all seem to know and feel that yellow lighting (popularly thought as Amber) is more suitable for fog but why is that so? Here is the science behind it by Daniel Stern:-
What is this Selective Yellow light?
The colour that we are talking about here is the “Selective Yellow Lighting“ and not the “orangish yellow” or “amber” lights colours that we see. These yellow selective lights are formed by removing the spectrum of light containing the blue-indigo-violet light so that the remainder of the light is prevalent.
So what does this light do and what makes it so special?. What is it then, that, explains the persistent subjective preference amongst experienced poor-weather drivers for selective yellow fog lamps , despite decades of white fog lamp prevalence?.
Selective yellow light can improve a driver’s ability to see in fog or rain or snow, but not because it ‘penetrates fog better’ or ‘reflects less off droplets’. In fact it’s because of the way the human eye processes different colours of light.
Blue, indigo, and violet are difficult for the human optical system to process correctly. They are the shortest visible wavelengths and tend to focus in front of our retina rather than upon it. To demonstrate this to yourself, after dark find a deep blue storefront sign or blue lights on an airport runway or something else that’s a deep blue light emitter against a dark background in the absence of white light—from any appreciable distance, it’s almost impossible for your eyes to see the blue lighted object as a sharply defined form; the edges blur. The blur effect is not present with nearby signs or lights of colours other than blue.
Blue also is a very difficult colour of light to look at; it stimulates the reaction we call glare. Within the range of allowable white light, bluer headlamps have been shown to be 46% more glaring than yellower ones for a given intensity of light. So, it seems culling the blue out of the spectrum lightens the optical workload and reduces glare. Thereby increasing visibility in the fog.
