Scientific researchers in neurology, psychology, and ophthalmology actually have found some preliminary evidence that the relaxing effects of green do not solely depend on cultural associations with leaves or meadows. Our eye perceives color using tiny sensors called cones. Certain cones are sensitive to red or green or blue light. However, overall they are the most sensitive to wavelengths at 510 nm, which translates to green light. Researchers hypothesize that this sensitivity to green objects might affect hormonal production or the circulation of neurotransmitters that in turn influence mood.
