Magic mushrooms seem to have a strange effect on color blindness

After self-administering a color blindness test, known as the Ishihara Test, the subject took five grams of dried mushrooms, which is considered a relatively high dose of psilocybin. He then took the Ishihara Test periodically over the next four months.

This test is composed of a series of flashcards that each feature a number made up of green dots, embedded in a background of red dots, or the reverse color arrangement. Before taking mushrooms, the subject of the case study scored 14 on the Ishihara test, which indicates mild red-green blindness. Twelve hours after the trip, his score had only improved by one point. The following day, however, the subject scored 18, which is past the threshold of ‘normal color vision’. By day 8, his score had climbed to a peak of 19.
