Color perception deficit
Explanation:
Color vision deficiency is the lack of ability to differentiate certain shades of color. The term "color blindness" can also be used to explain this visual challenge, but a very small number of people are entirely color blind.
Color vision deficiency can range from a mild condition to a severe case, depending on the cause. It can even affect both eyes if it is hereditary and generally just one if it is caused by illness or injury.
This condition is likely due to photoreceptors in the retina of the eye identified as cones. These cones have a light-sensitive pigment that allows us to identify different colors.
