What does "protan" mean?

A person with red-green colorblindness. The terms is short for protanopia (when the L-cone, which is used to differentiate red and green, is missing) or protanomaly (when the L-cone is present but impaired).

Fred is a protan, and has a hard time telling apart some colors.
