Do colours influence our behaviour much more than we realise?

yes! colors have actually been proven to affect your mood and your behavior. for example: food advertisement such as McDonald's usually use the color red, because red is supposed to make you think you feel more hungry. and another example is pink rooms are supposed to make you feel calm.

Yes.

Explanation:

This is my personal opinion, so don't take it too seriously if the question requires a factual answer, but I believe so.

Colors are interesting, and different colors can influence different things. For example, red, somehow, can make a person hungry.

Sometimes certain brands will use certain colors because they know that these colors will silently influence a person to use their brand instead of other brands.

Another example is a popular fast food restaurant, KFC. It uses red in its logo to induce hunger in onlookers, hoping that they'll stop by to grab a bite to eat.

So, yes, colors do influence human behavior much more than we realise, and understand.
