Answer to Question #194117 in Cell Biology for Kate

Question

Hi, in green colourblindness, is it true or false that they can’t distinguish red dots against green backgrounds

Answer 1

It is true. This kind of color blindness is referred to as protanomaly. The sufferer of this red-green color deficiency is not able to distinguish the red pigment from a green background. Protanomaly is usually mild and as a result, the sufferer can perform different day to day activities normally. The eyes perceive red as green when the L- cones are present but not performing well. However, the people suffering from protanomaly can be able to distinguish red only but not when placed with the green color.
