People who lack color receptors for the wavelengths of red are likely to experience

A) afterimages.
B) blindsight.
C) dichromatic vision.
D) cataracts.

People who lack color receptors for the wavelengths of red have dichromatic vision, meaning they can only see two colors (usually blue and yellow or green and magenta) instead of the usual three colors (red, green, and blue) that trichromatic individuals see. Afterimages and blindsight are not specifically associated with red color deficiency, and cataracts are a completely unrelated condition.
