Ever notice how specific colors have been associated with specific things? Like for example, the green has been associated with money because of the US dollar. Bitcoin is associated with the color gold. You’d notice that banks or digital payment services are color blue because it signifies trust. When you are wishing to create a product, branding is important and integral part of how the world views your product.
Good observation, OP. Color psychology is real and branding uses it a lot. Blue for trust, green for money, red for urgency, gold for value — none of it is random. Even in crypto, BTC = gold, stablecoins = blue/green vibes. New projects should think about this early, especially in ANN threads.
