Maybe 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.
