A person who is color blind has the reduced ability to see certain colors. Today I am going to talk about the most common type of color blindness, Deuteranomaly.

Deuteranomaly is the most common red-green color blindness. Deuteranopes can see two to three distinctive hues, while one with normal vision can see seven distinctive hues. This happens because the medium wavelength sensitive cones in a deuteranope’s eyes are completely missing. This medium wavelength, are known as the green cones in the eye. This wavelength in a deuteranope’s eye detects too much red light and not enough green light. As a result, greens turn to beige and sandy color, red and dark orange turn into a golden brown, some orange and green hues seem to turn yellow, and blue and purple stay the same except for the fact they have a gray tint that glosses over them.
