Colours and Biophilic Design

We have special relationships with some colours.  Around the world, wherever you ask, people are more likely to tell you that the colour blue is their favourite colour than any other shade.  Coincidentally, or not, blue is the colour of the sky on a very good weather day and the colour of a water hole when seen by a distance, so our sensory processing systems have very good reasons to find looking at this colour a pleasant experience.  Also, looking at the colour green has been tied to enhanced creative performance, which makes sense because in our prehistory when we were in a green space life was probably relatively easier (compared to when we might find ourselves in a desert, for example) and that might have given us some brain space to think about how to resolve life challenges we faced.  Also, when we see the colour red we get revved up, so much so that our analytical performance is degraded.  Long ago, when we saw the colour red, it was often because we were bleeding, someone we cared about was bleeding, or something we were fighting (perhaps so we could eat it) was bleeding—situations in which some sort of quick action was required.
