red/green colorblind (dont remember which technical name for it)
There are several types of red/green color blindess based on whether the medium or long wave cone is missing, leaving the other to pair with the short wave cone. There are also forms where all three cones are present but the pigments in one or more of them can have a different spectral sensitivity function than normal. This leads to decreased color sensitivity.

If you want techy stuff - the wiki entries will explain it. Tests can determine the specific type.
