text_A: In cerebral achromatopsia, a person can perceive only some colors even though the eyes are capable of distinguishing them all fully. Some sources do not consider these to be true color blindness, because the failure is of perception, not of vision. They are forms of visual agnosia.
text_B: Would a person with cerebral achromatopsia be able to distinguish a ripe fruit from an unripe one without tasting it?
DON'T KNOW.
