dichromatic vision

Dichromatic vision is a type of color vision where only two types of color-detecting cells (cones) in the eye are functional, instead of three. This condition limits the ability to distinguish certain colors, typically making it difficult to tell apart reds and greens or blues and yellows. People with dichromatic vision see a narrower range of colors and perceive the world in more muted tones compared to those with normal color vision. It’s often inherited and makes up a small percentage of the population, notably more common in males.
