^†Average of 10 settings on the Medmont C-100

^‡Average error score from two administrations

^§Limits of the match range on a Model 1 Nagel Anomaloscope

^¶D values are reported, indicating the most difficult plate read by the subject. D value quantitatively expresses the difference in chromaticity between the symbol and the gray background, measured as the distance (D) in the CIE diagram between the symbol and the background.
