Table 2.

A summary of testing results of each CVD participant for all tasks. The deficiency types are either protan or deutan. The severity categories differ across tasks—Rayleigh match: simple, extreme, or dichromat; HRR: mild, medium, or strong; FM100: superior, average, or low discrimination ability; AIM: simple or dichromat/extreme AT (D/E). The classification that is comparable and different from the anomaloscope classification is underlined. Individuals are grouped into protan and deutan categories based on their Rayleigh match results for better visualization
