Similar to these cases are those of the deuteranopes
mentioned in footnote 7.
are unable to distinguish red, yellow, and green when the brightness of all three colors is equal.
The neutral points for deuteranopes
, protanopes and tritanopes are around 498nm, 492nm and 569nm respectively.
Post hoc analysis for R signals shows that normals have significantly shorter response times than do all color-deficient groups except for protanomals, and that protanomals have significantly shorter reaction times than do deuteranopes
1) Protanopes and deuteranopes
are able to match all red-green mixture ratios.
Protanopes have a normal M gene, whereas deuteranopes
have a normal L gene.
Those with colour vision defects see the spot differently; for example protanopes usually describe it as blue or dark because their red sensitivity is reduced, and most deuteranopes
cannot see the spot at all.
Hidden digit plates seem to work better for deuteranopes
than other colour deficient individuals but they have an overall sensitivity of only around 50%.
