Why some people can't recognize certain colors
Only when the photoreceptors in the retina send information to the brain correctly are we able to perceive colors. There are different receptors for red, green and blue light. Working together, they allow us to differentiate between various colors and color nuances. Genetic variations in these cone cells can cause the colors to overlap so that they can no longer be distinguished.
