It all now made sense. These days, my color blindness is merely a nuisance. Often this requires asking salespeople color questions, especially in purchasing clothes. Sometimes I may believe that something black or dark gray is maroon or purple instead. From this people conclude I am hallucinating these colors.
Color blindness is incurable.
Some optical manufacturers attempt to convince the color blind community that a pair of tinted lenses can compensate for physiological imbalances, but by and large they are full of crap .
