Recent Examples of deuteranopia from the Web
Red-green color blindness is broadly organized into four types, protanomaly, protanopia, deuteranomaly, and deuteranopia, all of which have to do with how the cones in the eye function.
One of these is for players with normal vision; the other three cater to those with protanopia, deuteranopia and tritanopia (which correspond to people’s difficulties sensing red, green and blue light respectively).
The most common type of colour blindness, for example, is deuteranopia.
