Question about traffic lights? and got a better answer
Response from
No! Common sense dictates that red has the longest wavelength, so you can see it from the farthest away. From a distance where you can't see green or yellow anymore, you can still see red. This makes a huge difference for drivers! After all, if the light is green, you can in principle find out about it even later, and if it is red and you cannot go, it is better to find out as soon as possible - the braking distance of a loaded freight train is more than a kilometer. By the way, the first engineer who caused a big accident was named Dalton - was he colorblind?

I think he took the answer to his grave: You can make up anything now.

Red is an aggressive color - very much attracts attention - stop; green - calm, meaning drive through; yellow - middle between - get ready, attention This is my guess that he reasoned this way:

well red is understandably associated with blood if you go to green - characterized as calm calm, like you can go to this color

You know, this is very interesting! I think he took everything from nature: -Red is the color of danger, and green is the color of life.

I think by association, red is danger, green is tranquility, or maybe because of colorblind people on the road

In London, as you know, year-round fog, which does not absorb the red and green spectrum Trouble would be with the blue-yellow traffic lights.

The sense of color occurs in the brain when color-sensitive cells, the receptors in the human or other animal retina, are excited by cones. In humans and primates there are three types of cones - "red" "green" and "blue" respectively. Light sensitivity of cones is not high, so for good color perception requires sufficient light or brightness.
