Is it based on red being the color of an emergency or it doesn't look like a normal exit? Is it because they did studies on what is easier to see in smoke? Is it because green or red lights are cheaper?
The conclusion of a master's thesis at Lund University / LTH (Sweden) onto that topic provides some information on why green is chosen over red:
When it comes to the performance of green light in comparison to red light, we have
seen that under white smoke conditions, on average, green light has performed better
than red. While under black smoke conditions, red light was the better of the two, in
line with the previous research. Nonetheless, the reason why green is the most
commonly used color still remains independent of its performance against red light. As
previous literature has proven, people perceive green as safe and tend to choose it over
red in these situations.
I believe in Australia, by law it has to be green, except for parliment house because it'd ruin the aesthetic, so its allowed to be red (take with grain of salt, it's been a while since I went to Canberra).

Canada's building codes since around 2014 require the green man pictoral exit sign.
Old buildings have EXIT or SORTIE signs in red. Some renovated buildings have a mix of both.

Ahh yes I was surprised that they have the European (or just international idk) one

It's because the pictogram doesn't require knowing French or English (depending on where in Canada you are)

Ah that makes a lot of sense

australia has them as well, so i’d assume general international

This is a funny map because it's super informative and I'm not sure I've gotten anything of substance out of it.

I'm sure it'll be super useful in a fire :)

Is that a threat? W-why would they be in a fire?

With defunding fire fighters and climate change, you never know. Thank God we have that space lazer to control the weather, otherwise I'd be worried

Because they keep moving people's desks and staplers. I saw a documentary.

The same reason you might if you keep asking questions …

What's with NYC and yellow?

I was intrigued too but it just seems to be red. Not sure why they've singled it out

I apparently live in a red state but my workplace (in state) is green
SubArcticTundra@lemmy.ml · 11 pts · 1y
It seems many states actually allow both

Now we just need to place them under the smoke at floor level
rc__buggy@sh.itjust.works · 4 pts · 1y
And green. At the floor and green. Green, at floor level.

Because the hyphen or space keys are so far away.

The green states should just secede.
