Why do the Japanese call the green light "blue light"? What is the reason?

When friends are traveling in Japan or watching Japanese cartoons, do you find that Japanese people are used to shouting green lights at traffic lights? Blue light? ? It's not that you heard it wrong, and it's not that the subtitle group typed it wrong. This is a habit of the Japanese people and even written into the law! Let me tell you the specific process!

1. Because of Japan's unique cultural habits, the green light is called? Blue light? !

In Japanese culture, Japanese people are used to saying that green is cyan, and cyan means blue in Japanese culture! Even Japan now has this cultural habit. In Japan, they are used to using blue words to describe green objects. For example, a green apple will be called a green apple, but blue means blue. In this way, it will become a blue apple. ....

2. Why do you call it? Blue light? From a slip of the tongue! Later, it was habitually written into the Japanese traffic law!

It is said that when the 1930 traffic signal was first introduced to Japan, the newspapers that reported the news to the public mistook the green light in the traffic signal for a green signal (which means blue signal in Japan). Then this false statement spread in the society, and discussions and exchanges between people are all such false statements! When people realize that this is a mistake, it is too late, because people have already put? Blue light? Accustomed to it, it is not easy to change! So in 1947, the Japanese law was wrong? Blue signal light? Written into the traffic law of Japan!

Japanese like blue very much, and they are too lazy to change back to green!

Little friends know that there are few colors in ancient times, because the process of color extraction is very complicated! This is why no national flag is purple, because the production cost of purple is too high! In ancient Japan, red, white, blue and black were the most common colors. People in ordinary families draw pictures, and green things are painted blue. Over time, in the eyes of the Japanese, there is no difference between blue and green. Everyone likes blue, an ordinary and clean color!
