Some area in Scotland and Japan switched to blue street light. As a result, crime and suicide rate in the area are decreasing.

In year 2000, a blue street light was introduced in Glasgow, Scotland to improve the city landscape. The number of crime in the area are getting lower after that.

Similar thing happen in Nara, Japan when the police started to set up blue street light around the neighborhood. The crime rate is reduced by 9 percent.

The Japanese also switched the light on the ends of platforms at Gumyoji Station in Yokohama to blue. As a result, there are no new suicide attempt was reported.

There might be several reasons for this, some of the reasons might include :

• The unusual color cause people to be a lot more alert and caution.
• Blue light might make people feel calmer compared to red and yellow.
• Blue light usually associate with police, making people feel like the area is watched more strictly by law enforcement units.

It is still unknown if the crime and suicide rate will remain low when people has become accustomed to the blue light. Nevertheless, it is very interesting to see if a simple change like this can bring such a great impact.
