Blue is in!

And why shouldn’t it be (always)?  Research consistently shows that no matter where on the planet you ask, people are more likely to tell you that blue is their favourite colour than any other shade.  There are fundamental reasons for our blue preference:  in our early days as a species blue was important to us, it was the colour of the sky on a fair-weather day and a water hole seen from a distance—and fair-weather days and water were crucial to our survival.  We’re using the same sensory apparatus now as we did aeons ago, and it seems we’ve inherited from proto-humans mental pleasure in processing the colour blue.
