“I like blue,” “That person likes green”… It’s heartening to know that these colour preferences aren’t just a passing fancy.

I’d like to tell you about something I came across recently, which I found really interesting. It’s something called the “Ecological Valence Theory (EVT)”, which was proposed by psychologist Stephen E. Palmer and others.

To put it simply, this theory suggests that our love for colours comes from our fondness for the things that are associated with them.

Blue is such a popular colour, isn’t it? It’s always at the top of the list in colour surveys all over the world. It’s so lovely to know that this preference is something we can all agree on, no matter what our culture or gender. I think it’s something we all have deep down, as a way of protecting ourselves.

Blue is like the sky and water, and it makes us think of safety and all the things we need to survive. That’s why we all love blue, right?

Another reason blue is chosen is probably because there are so many positive associations with it (like the sky and the sea), while negative associations (like poison or decaying matter) are very rare.

Our brains have a way of ranking things, and blue is like the star student with hardly any bad points.

If you’re ever unsure about choosing a gift or selecting interior decor, don’t worry! It’s completely normal to feel this way sometimes. If you do, it might be a good idea to start with shades of blue.
