Applying the psychological effects of colour : the case of Japanese train stations

A persisting social problem that Japan faces is its high suicide rates ranked among the top of OECD countries. In many cases, attempted suicides take place at train stations, with people ending their lives by jumping off the platform. Attempts to prevent these problems are now in full swing by implementing different psychological measures.

One such case is the implementation of colour psychology intended to calm people's mood through blue lights before they act impulsively. Research from the University of Tokyo shows that this implementation has indeed been effective.
