Update on color blindness: Display monitor RGB adjustment
It finally dawned on me computer users with some color blindness
can tweak RGB
in the display monitor screen, to see "more normal" images. So, I bumped up the red a good bit, lowered the blue a bit, and see more on the screen. I will continue to tweak this. Perhaps one day I will be able to see all the Ishihara
numbers, on my computer screen.
