Question

Quizplus · Accepted Answer

People with red-green colour blindness have a genetic mutation that affects the photopigments in the cones that detect red and green wavelengths. This results in a reduced ability to distinguish between certain shades of red and green, as well as other colors that rely on those wavelengths, such as brown or purple.
