If you're driving in Japan, you're likely to be eaten by a grue light. That said, we actually mix some blue into modern green lights, so that colorblind people can distinguish the two colors.

In official CalTrans terminology, the yellow lights are called "amber lights" -- so we have our own weirdness in the U.S.

The same character is used in Chinese where it also refers to bluish-green, tending closer to green than blue: https://en.wiktionary.org/wiki/%E9%9D%92 There is also a character for a much deeper blue: https://en.wiktionary.org/wiki/%E8%97%8D

True, see the Pokémon case with the original Green edition and then the Blue one.

The article doesn't really make this clear, but in modern Japanese 青 as a color just means blue, unambiguously. There are a lot of set phrases where it refers to green, but these have really only survived in cases where the color of the thing is obvious from context. When Japanese 青 is used to specify an unknown color it's just blue.

That's because they're a mix of yellow and orange. They're called amber across Europe too, officially anyway. :)
