@jeanne-mayell Yes! If you have done any work in visual arts, I think you definitely notice many different shades of colors. I do a lot of nature-based artwork, esp. botanical art, so there are many, many shades of green! :) I often work in colored pencil (Faber-Castell Polychromos), so I tend to think of which pencil I would use for something..."oh, that is Carmine red or, no, it is more an earthy Pompein red..." And then you can get into layering colors...fun stuff :)
I have also read a lot of nde accounts where people report seeing colors they can’t see in our waking reality, so I’m delighted that came up in the article. Also, foragers, particularly in indigenous cultures, tend to have heightened color and smell perception.
I learned a great deal about colors from my 64 count box of Crayola Crayons. Who didn't like using the name "burnt sienna"? I loved periwinkle pink carnation and mulberry. I loved sorting my crayons by color too.
Fun fact. When my children were younger, our dog would eat the crayons they left out and poop a rainbow of different colors. I never thought to identify the different shades of the colors he pooped by name though...thank goodness. hahaha
One would need a new lexicon of "dirty" colors. Scat-scarlet? Poopish-purple? Turdy-teal? The lawn is the limit.....Imagine how disturbing it could be to a tetrachromat!
