[a fool in paradise]

>>Operating on the theory that exposure to blue light has a calming effect on one’s mood, rail stations in Japan began installing these LED panels as a suicide-prevention measure in 2009.

I find blue cast LED lights to be psychologically cold and hard, not “calming” or “suicide avoidance”.

I love blue lights. Green also. Especially as outdoor lighting grazing a textured surface such as a stucco or rough stone wall.

As for blue indoor lighting, I guess that can be pretty soothing as well.
