I 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.

I’d say here in the US the LEDs skew much more blue than the incandeswnts they replace. Almost a teal.
