Certain colors are known to have certain psychological effects – if we assume that our brains’ emotional responses to “objective” colors are uniform, then if enough of us were not seeing the same colors the same way, this could not have been an observable phenomenon.
The thing with color psychology is that it could definitely be affected by factors such as personal preference and experiences, culture and whatnot. But then I Googled and read about it for a while and some people say what I am and some say it’s a consistent physiological reaction. So I don’t know. But I never thought about that so thank you.
