I remember there was an article about companies using colors as a marketing/advertising strategy. Remember Steemit used emerald as its logo's color? Subconsciously people get attracted to the color because I think it means reward. Also there are some credit card companies using emerald as their logos' color just to lure people to "rewards" when in reality it means more debt. It's crazy to think.

But I also used the same color for my startup travel agency logo. Emerald, because it's the color of our waters - it makes sense anyway LOL. I profited pre-covid.
