That's just fair - pedestrians aren't detected either

Pedestrians have a button to press to let the signal know they exist. Until we invent car-hands, that seems equivalent enough.

In a number of those systems, the buttons are a placebo that are wired to nothing. [1] [2]

Amber, the color of traffic lights, waves of grain and... pretty much nothing else. Reminds me of (grammatical) petrels: https://www.kith.org/words/lists/petrels-list/ It's as if when modifiers and nouns sense they are dying in a language, they clutch on to one another for support, and eventually become like a single unit.

I think there's also a naturally-occurring substance that's amber-colored, but I can't remember what it's called.

I've lived here in Japan for the past 18 years and I still tend to call them "midori", much to my wife and children's amusement. But, the hue of the lights are actually somewhere between the typical USA green lights and a blue. My wife (and kids) swear that it actually is a BLUE-hue light whereas I still see Green. SAME issue with the sun. I say it's yellow, they say it's red, and it's not a kanji issue... $0.02.

Recently been enjoying a couple of Japanese HD-quality train webcams, that have some auto and pedestrian traffic signals visible in the shots. They look green to me.

Obligatory aside: It's not easy being green.

I've never heard "amber" used as a modifier for "amber."

"Quick, bring me the amber amber, Amber!"

I didn't write the comment very clearly, but the petrels were a hint I was talking about language and usage, not simply objects in that part of the spectrum.

Ale is a notable omission, but the candidates dwindle.

I've been living in Japan for about 25 years and a lot of Westerners get confused over this.

Concepts like "blue" and "green" are abstract. The word 青 covers a different part of the spectrum than the word "blue".

People get hung up on "what's the Japanese word that means X", but often there is no word that means X. There is no distinct concept for X in Japanese. And this goes far beyond color names.

European languages largely share a common cultural heritage and concepts tend to map between them relatively easily, but many cultures aren't like that.

The Japanese stoplight colors are just the tip of a very, very deep iceberg.

No. The official position (as quoted by someone who actually asked the Highways Agency) is that the ability to actually tell red from green is not necessary for traffic lights. The sequence of lights and the positions of the lights is adequate. * http://andrewhenley.co.uk/2012/02/colour-blindness-and-red-t... The statutory instrument that governs traffic lights does not actually state anything more specific than "gre…

An easier explanation for more blue in traffic lights as they switch to LEDs is that blue LEDs are just boringly cheaper.

What? Blue LEDs used to be the most expensive. Say $1 per in bulk vs 2 cents for red or green. Has that gone full circle?

Nonsense, it's white or yellow or red or otherwise, depending on the viewer and time of day and weather and whatnot. But the topic here is how people describe things, and in Japan the sun is commonly described as red.

maaark probably referred to that the sun actually is white, but may appears with different colors if you see it through a filter (atmosphere): http://solar-center.stanford.edu/SID/activities/GreenSun.htm...

It's white by some definitions and not by others, there's no single objective truth to the matter. But none of this has any relevance to the post originally being replied to.

That is my understanding. Blue LEDs were last to be developed so they carried their R&D costs until more recently, but between efficiency breakthroughs and mass production improvements have passed through to being the cheapest to buy, especially in terms of lumens per dollar in places where you really need brightness such as traffic lights or overhead LED lighting in homes.
