It's just starting to rain and I have time only to pick a few strawberries and some kale. On my way back to the cottage, I pick one of the red roses and discover that next to the red strawberries
Thinking about gradations of color and the glory of being able to see them, I started reading a little bit about what is often called being "colorblind" but is more accurately called color vision deficiencies.
Excerpted from What is Colorblindness and the Different Types
People with normal cones and light sensitive pigment (trichromasy) are able to see all the different colors and subtle mixtures of them by using cones sensitive to one of three wavelength of light - red, green, and blue. A mild color deficiency is present when one or more of the three cones light sensitive pigments are not quite right and their peak sensitivity is shifted (anomalous trichromasy - includes protanomaly and deuteranomaly). A more severe color deficiency is present when one or more of the cones light sensitive pigments is really wrong (dichromasy - includes protanopia and deuteranopia).
5% to 8% (depending on the study you quote) of the men and 0.5% of the women of the world are born colorblind. That's as high as one out of twelve men and one out of two hundred women.
And here is a link to a free on-line test. Parents and teachers might find this website especially helpful as undiscovered vision deficiences can cause multiple difficulties for children .
The deck....the REDwood deck is coming along. Of course weather and time will turn this bright wood to some shade of gray like the old fence it abuts.
Well, I better go wash my kale and ponder its silvery blue green hues into some edible form.
'til next time then...
