Blue Traffic Light: You must have seen green, yellow and red traffic lights, but you may not know that there is a country where blue traffic lights are used.

Blue Color Traffic Light: You've rarely heard that a traffic light is also blue. This may surprise anyone, but there is a country where there are still blue traffic lights, and 99% of people will not know about it. That's quite interesting, but is it true? Let's know about this in detail.

There are blue traffic lights in Japan.

Actually, this claim is linked to Japan. Some traffic lights in Japan look a kind of blue color instead of green. But it is not completely blue, but a very dark shade of green.

Why are there blue traffic lights in Japan?

The reason for this is a special thing about colors in the Japanese language. In Japanese, the same word "ao" is used for both blue and green. When traffic lights were first installed in Japan, the word "come" was used to signify "go" even though the lights were green.

Gradually, a separate word for green "midori" was used in the Japanese language. But in old documents and in the minds of many, the word "come" remained associated with the color green. That's why, when it came to standardizing traffic lights in Japan, an agreement was reached. Instead of green, a color was chosen which is between green and blue. This color is green, but slightly darker, due to which it appears blue.
