People are easily manipulated by colors, I think this is likely to be
a leftover from millions of years of evolution, where humans needed to
identify danger (wild animals) and gain (food), but it can work against
modern humans.
Eg. Just turning a word doc red text and with a bright red background
will make it seem scary.
Or for traffic lights or X/Tick: Red is bad, green is good, yellow is
warning
It’s from evolution, it’s from society, and it’s from pattern
recognition indeed. It likely won’t change anytime in the near future.
Or it could mostly just be the fact of darwinism: How do you act like a
normal person without sensory input from the eyes??
