I understood what the green color of EXIT signs means, and why the red EXIT signs phased out in Canada.
We don't have the green walking man logo in our EXIT signs in Israel, but the text "EXIT" in hebrew instead, but it printed in green as well.
Only the "No Exit" signs in Israel are printed red, and this is because these signs are on doors that may leads you to nothing and you might be caught there and wouldn't find a way to escape, if you enter there.
The green and the red color used as a mode symbol.
Green means safe or no dangers and red means danger and is usually a warning color.
Therefore red Exit signs is illegal, as they causes much confusion because they contains an Non standard combination of a positive sign that says a safety exit with a warning color (And the origin of the used lightsources isn't an excuse to deviate the worldwide standard (What is more important: Brightness over the nature of the sign color, or a less bright sign with a standard color? [Indeed, in Israel, Electrozen produce green LED Exit signs {With either green or white LEDs, but the text always green, regardless of the LEDs color} that are very dim, much dimmer than a hypothetical green version of Canada incandescent EXIT/SORTIE signs, but they are still pronounced in the darkness]).
I think that except Canada, and i don't know how the status in the US about the color of the Exit signs is (Through i saw pictures of american LED Exit signs [The ones with the seperate incandescent/halogen emergency lights] and LED retrofits for incandescent lamps for Exit signs, that had red LEDs instead of green LEDs), no region in the world uses red color for EXIT signs as this is an unusual and not standard.
