Pridmore, 2014) [L.sub.R] values over one for real protanopes and the pseudoachromatic greens (they see such stimuli lighter than do common observers) but [L.sub.R] values below one for real deuteranopes (they see the pseudoachromatic greens darker).
Such transformation produced [h.sub.uv] and [L.sub.R] values similar to those provided by real protanopes but not by real deuteranopes. Otherwise, the software tool named Coblis produced different colour transformations for both dichromacy types, but they were always inaccurate because of the systematic errors found both in [h.sub.uv] (for example, about 140[degrees] instead of 183[degrees] for pseudoachromatic green and protanopia) and [L.sub.R] (for example, [L.sub.R] was over one for the pseudoachromatic reds both for protanopia and deuteranopia, although predicted [L.sub.R] values for protanopia and pseudoachromatic reds were under one).
I had more of Tritan type, which is 25.8%, Deuteranope 4.7%, and Protanopes 4.7%.
Group I: (Out of 85 subjects) Red-green deficiency: 16 (8 protanopes, 8 deuteranopes).
The results show that deuteranopes are less likely to notice road traffic control devices than are observers with normal color vision, with the exception of yellow warning signs and blue parking signs, which have the same conspicuity for both observer groups.
However, deuteranopes perceive any red color in road signs as dark yellow.
This is also an explainable result: Deuteranopes see green as grey, or as a grey with a yellowish tinge.
The change in strategy induced by the search instruction enabled deuteranopes to improve their hit rate performance to a greater extent than did color-normal observers (Figure 3).
Protanopes (who lack the long-wavelength-sensitive red cone) have a loss of color vision as profound as that of deuteranopes. The more severely affected deuteranomals and protanomals will most likely perform similarly to the deuteranopes in this study because the more severe forms of these defects approach the loss of color perception experienced by deuteranopes.
Deuteranopes made significantly more errors than did any other group (p .001), with 30% and 23% errors for R and Y signals, respectively.
For example, our deuteranopes showed the greatest increases in response time--53% for R signals and 85% for Y signals, relative to those of normals--whereas protanopes showed increases in response times of 35% for R signals and 53% for Y signals.
