Black is Magenta
A demonstration of the inverse of white is green
In the human retina most of the photoreceptors detect green light and use the information to perceive edges. Rod cells, that detect tiny amounts of green, allow you see shapes by starlight but make images in shades of gray.
Detecting green light does not help us perceive green things because white and lots of colors contain more green light than do things that appear green. To see what we call green we have to detect the absence of red and blue.
I have a new proof that white is green based on the prism experiments of Sir Isaac Newton, Robert Boyle, and Johann Wolfgang von Goethe. My friend Tom Eatherton suggested that logically if white is green then black must be magenta, and that is also demonstrated
White is Green:
1) On an RGB display such as a computer screen, create a vertical white line one or two pixels wide and 2 cm high on a solid black background.
2) View this line looking through an equilateral triangle prism held vertically with the apex pointing to the right. You will see three lines of color, red green and blue. The spacing between the green and blue lines will be greater than the spacing between red and green.
3) Create an image of three vertical lines that reverses the image seen through the prism, blue, green and red. Make the red and blue lines a bit shorter than the green line. Duplicate the spacing between the lines of color as seen through the prism.
4) View the three lines through the prism held as it was in step 2. You will see a single white line exactly where the green line appears. The white line will have a green tip.
Black is Magenta
1) On an RGB display such as a computer screen, create a vertical black line one or two pixels wide and 2 cm high on a solid white background.
2) View this line looking through an equilateral triangle prism held vertically with the apex pointing to the right. You will see three lines of color, cyan, magenta and yellow. The spacing between the yellow and magenta lines will be greater than the spacing between magenta and cyan.
3) Create an image of three vertical lines that reverses the image seen through the prism, yellow, magenta and cyan. Make the yellow and cyan lines a bit shorter than the magenta line. Duplicate the spacing between the lines of color as seen through the prism.
4) View the three lines through the prism held as it was in step 2. You will see a single black line exactly where the magenta line appears. The black line will have a magenta tip.
In the spirit of the Enlightenment from which the scientific method arose I need to have my experiment duplicated and documented by another researcher.
The demonstration explains the spectrum of visible light, the human perception of color as a mixture of primary colors, how computers make color, and most important, validates Goethe’s proposal that the dimensions of color are light/dark and warm/cool.
The Black is Magenta demonstration is especially beautiful, almost magic, because black appears on a screen that is all white with a few very bright color lines. It is also important because it is the inverse of White is Green and proving the inverse of a proposition is a strong check of the underlying logic.
