I hope this doesn't sound like a dumb question, but I just wanted to ask since I don’t really have an online group where I can talk about stuff like this seriously. This is just based on something I’ve noticed…

why is it that most popular casinos use a black and green color combination? Is there some kind of science or psychology behind it? Does it actually attract more gamblers? just thought I’d throw the question out there, who knows, maybe one day I get lucky and open my own casino (daydreaming lang  ).
