University of California, IrvineThe Ishihara test, used most widely, is intended for diagnosis of congenital red-green deficiency (“daltonism”), differentiating its two types, protans and deutans, and severity (mild, moderate, or extreme) [6, 7] (see Paramei and Bimler, “Protanopia”; Paramei and Bimler, “Deuteranopia”).The Hardy-Rand-Rittler (HRR) test contains additional six … You would not flunk the Ishihara. Functional tetrachromats (1 in millions of people) see much wider ranges of colors than normal trichromats, and they pass Ishihara with ease.
