Re: Why Japan has blue traffic lights instead of green
#32Maybe Korea also had blue traffic lights in the past. But they still call green traffic lights 'blue' even though all of them use a green coloured light. I think the use of blue to mean both blue and green has also been present in Korea for a long time. I wonder where it came from? In my limited experience if Korea and Japan share something culturally it often has its common derivation in Chineese tradition.
青天 - clear skies
青草 - green grass
清葡萄 - 청포도 - white grape
Re: Why Japan has blue traffic lights instead of green
#33I used to wonder, as a kid, why most traffic lights in my region of Germany were red, orange-yellow and obviously turquoise. I remember drawing traffic lights (I loved drawing road layouts when I was young) without any use for the green pen. Nowadays, they all seem to be very much green, at least the new LED ones.

綠 is used in Japanese for the color of green tea, but they use 青 for the green light
There's also 翠 in Japanese to mean a bright green, which in Chinese also has a blue connotation (based on the color of the kingfisher who dives 淬 to catch fish)

Traffic lights are still fine for colour-blind people aren't they? The order of the lights doesn't change.
Horizontal lights are not consistent across countries. The linked article has an image of a Japanese horizontal traffic light with red on the right, whereas an American traffic light would have red on the left.

The Greek had no word for blue, which is the reason Homer described the sky with different words. But I never heard that the sky was green-isch.
While on the other side the Greek had more similarities between green and yellow.
