Well, it states “total color blindness” so, effectively none.
My point is that when you have “total color blindness” it simply means you cannot effectively discern the difference of of color. That does not mean “black and white.”
For example, everyone has a blind spot in their eye where the optic nerve passes through the retina. This area has no photoreceptor cells, so there is a spot in each eye that cannot see. When you look through one eye and close the other, do you see a black void spot? Is it a blank white area? No. It’s just… nothing.
No. The article states “total absence of working cones in their eye retinas, leaving them with only rods”.
I’m trying to say that not being able to see color does not mean black and white or grayscale, it means the brain does not decipher color hue.
My example of the blind spot was to outline that a lack of receptors does not mean black, white, grey, whatever. It means a lack of signals to the brain to process anything. In the case of lacking cones, it means an inability to process color. When it’s described as “grayscale” that’s to help people understand a concept that is difficult for some people to grasp.
Think of it this way. Black is like 0, White is like 1, and Grayscale would be a float (decimal) between 0 and 1, while Colorblind is like NULL.

Are you thinking of cerebral achromatopsia, rather than congenital achromatopsia? As far as I can tell, rod monochromats really do see in grayscale.
