Ok, I don’t mean to belittle or denigrate the knowledge or opinions of professional biologists, geneticists, etc. They know that the concept of race may only be useful in identifying a few genetic traits appearing in certain groups of people and not others. We share 96% of our DNA with chimpanzees (see https://news.nationalgeographic.com/news/2005/08/chimps-humans-96-percent-the-same-gene-study-finds/) and 99.9% of our DNA is common across all races ( see http://www.genomenewsnetwork.org/resources/whats_a_genome/Chp4_1.shtml).
It makes about as much sense to apply racial classifications based on skin color as it does to create racial classifications based on brown-eyed, blue-eyed, red-haired, blonde-haired, or brown-haired people.
Now, if you’ve followed me up to this point, let’s take a look at the physics of colors. The different colors most humans can see are due to the red-, blue-, and green-sensitive color receptors (cones) in our retinas. In combination, those three cone types allow us to see red, orange, yellow, green, blue, indigo, violet, and certain transitional colors between them. These colors are derived from the different wavelengths in ambient light. White is the sum of all color wavelengths and black is the absense of any color wavelengths.
The way colors mix in physical light is different than the way they mix in pigments of paint, so don’t be confused by the two different media.
What we see with our physical eyes are the light waves reflected off the objects around us. Physical properties of those objects (people, animals, plants, things, etc), cause different wavelengths of light to be absorbed by those objects. An object that is actually green would be seen as the sum of the rest of the colors that are not green; in other words, a mixture of blue-red. A red object would be seen as blue-green. A blue object would be seen as red-green. The cones in our retinas pass a color negative up our optic nerves to our brains , just like color-sensitive photo paper that has been immersed in developer fluid.
Some of you are probably beginning to see where I’m going with this.
The people we call blacks, whom we see as black or dark brown are actually white or light tan, or any other color besides black or dark brown. The people we see as white, pink, or light tan are actually black, dark brown, or dark blue-green.
Anybody who has put up a sign saying “whites only” would be advised to take down those signs before there is a misunderstanding as to intent.
I’m jus’ sayin’.
