 "Which country has red, yellow and blue traffic lights? Why is green not used?")
From childhood we are taught that green means go and red means stop. Young children sometimes mention traffic lights in their games too. Many poems have been composed in which the colors green, yellow and red are mentioned. But did you know that there is one country in the world where all those poems and learned things are proved wrong? This is because yellow and red lights are used in this country (Which Country Has Blue Traffic Light), but blue light is used instead of green to control traffic.
Let us tell you which country it is. The name of this country is Japan. Why not use green color in traffic lights in this country famous for its technology, better facilities and strong economy? Indeed, there is something peculiar about the Japanese language, which has led to all this manipulation. According to the Atlas Obscura website, for centuries in Japan words were coined for only four primary colors, black, white, red, and blue.
The Japanese are confused by the words
In Japan blue is called Ao. If we were to talk about something green, it should be called AO. This continued for several years. But as many centuries passed, the word Midori came to be used for rabbit. Midori was also Ao’s shadow. The word changed but people did not adopt that name. People called Hare as Ao.
This is why blue light is used
Now come to the green light of the traffic signal. Following international standards, the Japanese government used the color green for signals. But in Japan’s official traffic regulations and documents, the green light was called AO, not Midori. The government was opting for green but linguists and common people were opposing it. He said that if AO color is to be selected according to Japanese rules, then the government should also use it. Amid external and internal pressure, the administration chose a third path. In 1973 he chose turquoise light. He claimed that his green color is a shade of blue. Meaning a color that is green but looks blue. People visiting Japan believe that the country has blue traffic lights, but the government there argues that they are not blue, but a shade of green that looks blue.
