Did you know you were a trichromat? Why we all need green

With the COVID-19 need to isolate being slowly lifted, pictures of people flooding the parks, beaches and trails appear from every country which has been in a shut down.
I’ve always thrived outside, whether it’s sitting in the morning sun with a cup of coffee, hiking a trail, a walk by the sea or fly fishing in a stream.  Reading this information on the color GREEN has given me added insight on why nature is so appealing to me . . . Peggy

We’ve published posts on thepositive effects of falling water on our brains and now here’s evidence that we need green in our lives.
Green is the most universal interpretation of nature imagery, a symbol of the environmental movement and healthy living.
  • The human eye can see green better than any other color in the visible spectrum
  • The color has many associations, from disgust to tranquility

Green (the mixture of blue and yellow) can be seen everywhere and in countless shades.

We see green with ease because of how light reaches our eyes; the human eye translates waves of light into color.
When we see a green Woofer-dog, the color that we see is the light reflected off of the surface, the cones in our eyes process the wavelengths and tell the brain what color is being observed.

Kermit and I know It’s GOOD being GREEN

Humans are trichromats, meaning we perceive three primary colors: blue, green and red. The retina in a human eye can detect light between wavelengths of 400 and 700 nanometers, a range known as the visible spectrum.

Each primary color corresponds to a different wavelength, starting with blue at the lowest (400 nanometers) and red at the highest (700 nanometers).

The color green resides in the middle of the spectrum, at around 555 nanometers. This wavelength is where our perception is at its best.  Because of its position in the center of the spectrum, both blue and red light waves are enhanced and better perceived with the help of green waves.

Your environment

Green space sweeps the planet. Before skyscrapers and suburbs popped up, our ancestors resided in forested regions full of greenery.
As they scavenged for food, the ability to differentiate between colored berries against the backdrop of green foliage was critical for survival.

The Evolutionary Advantage of GREEN

“The evolution of eyesight and the increasing ability to detect color with fine detail gave our primate ancestors an evolutionary advantage over other mammals who could not discern such differences as well.
Color changes in leaves, fruits and vegetables can indicate age or ripeness and even offer a warning that something may be poisonous or rotten.
Today, we continue to use this ancestral instinct at a farmers market or grocery store.”

Keeping you calm

“Some scientists and researchers also believe that because our eyes are at the peak of their perception to detect the wavelengths corresponding with the color 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.”

Helping you live longer

“A 2016 study found that living in or near green areas can was linked with longer life expectancy and improved mental health in female participants. Researchers from Harvard T.H. Chan School of Public Health and Brigham and Women’s Hospital compared risk of death with the amount of plant life and vegetation near the homes of more than 100,000 women.”

“After the eight-year study was completed, the data revealed that participants who lived in the greenest areas had a 12% lower death rate than women living in the least green areas.”

“With more green space, study authors said, came more opportunity to socialize outdoors. Additionally, the natural settings — compared with residential regions where plants and greenery were sparse — proved to be beneficial to mental health.”
Of those who did not live in greener areas, respiratory issues were the second highest cause of death. The study indicated that less exposure to polluted air may have been one of several reasons for increased life expectancy among for those who lived in green areas.

  1. Wow, Peggy, this is so interesting. About a year and a half ago we learned we had to move yet again. It was distressing to say the least. We decided we could move into an apartment building as the last two houses we rented were more or less meant to be long term rentals – that didn’t work out. At any rate we looked at several places around the city and I could not see myself living in any of them until we came to see the place we live now. I wanted it because the backyard backed onto a green space with a pond! That spelled heaven to me. I am a country girl at heart and the idea of living in areas that are densely populated and surrounded with busy streets and concrete actually made my spirit hurt. This article makes a lot of sense to me. Thanks for sharing!
