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.
