Why are traffic lights red, yellow and green? solar street light-litersolar

I don’t know if you have ever thought about why you choose red, yellow, and green for the color of traffic lights. There are many colors, but these three colors have been decided. Let’s explain it to you. Speaking of this problem, let’s Let's take a brief look at how this traffic light appears. It was in 1868 that the world's first traffic lights appeared on the streets of London, England. At that time, the signal lights only had two colors of red and green, and it was far less advanced than the current street lights. It could only rely on the police to stand next to the signal lights and control the color change by pulling a wrench. After that, this kind of traffic lights gradually became popular all over the world. It was not until 1920, in Detroit, the United States, that the yellow signal light was added for the first time to remind drivers that the signal light was about to change from green to red. So why use red, yellow and green instead of other colors? It starts with red. Of all the colors, red is the easiest to grab people's attention. Probably because red is the color of blood, red has always been given the meaning of 'warning' and 'forbidden' in various cultures. Therefore, it is a matter of course that the signal light representing the prohibition of passage is chosen to be red. So why use green for allowing traffic? That's because red and green, like black and white, were widely believed to be complementary colors at that time. Since red represents no passage, it makes sense to use the opposite green to indicate permitted passage. And yellow, a color between red and green, was chosen to serve as an intermediate signal to indicate that the traffic lights were about to change. Finally, let me tell you a little secret, the traffic lights in most countries are not actually pure red and pure green, but slightly yellowish red and slightly bluish green. This is mainly to make some people with red and green. People who are green-blind can more easily distinguish the color of a signal light.
