Some scientists and researchers also believe that because our eyes are at the peak of their perception to detect the wavelengths corresponding with the colour green, the shade may calm us down.

With less strain to perceive the colors, our nervous system can relax when perceiving the tone.

This sedative quality of green may explain why there is so much of it in hospitals, schools and work environments. Historically, actors and actresses would recess to green rooms after so much time looking into bright lights on stage, though modern “green rooms” are rarely painted green.
