Figure 6 shows that none of the Coblis simulations was accurate both for protanopia (rightmost bars in Figures 6a and 6b) and deuteranopia (rightmost bars in Figures 6c and 6d).
R] values regarding Variantor and Coblis for deuteranopia were inverse for pseudoachromatic greens (positive for Variantor and negative for Coblis) but not for reds.

Data were statistically analyzed on SPSS-16 to find out frequencies of protanopia and deuteranopia among the studied population.
Gender wise frequency distribution of protanopia and deuteranopia in Quetta.
Only one class of defective color vision was studied because the inclusion of all four of the most common types of defective color vision -- protanopia, deuteranopia, protanomaly, and deuteranomaly -- would have increased the complexity of the experiment, especially considering that persons with the latter two vary quite a bit in the extent of their loss of color discrimination.
The diagnosis of deuteranopia was established by failure on the Ishihara Test and by finding a full matching range at the Nagel anomaloscope without reduction of yellow brightness at the red end of the matching range.
Protanopia and deuteranopia are inherited as an X-linked recessive trait.
The inheritance pattern for protanomaly and deuteranomaly is the same as for protanopia and deuteranopia.
