Metatron, the Wiki article you linked is flawed, in particular because of this graph:
There are two issued with this:
1. The gaussian envelope curve implies that the brain has infomation about the wavelengths of light falling on the retina, when all it has is the three (for trichromats, at least) cone cell type signals.
2. The preponderance of turquoise in the peak, when yellow is the brightest colour (having the strongest overall cone cell signal, due to the high overlap between the MW and LW cone cell response , as shown in another graph on the page (one that actually is correct).
I tried asking for scientific references for the "color sensitivity" graph, but none were forthcoming. I strongly suspect that it came out of someone's head, and that someone had a more artistic than scientific bent, the subject being of great interest to artists.
3. Note also that there is almost no green in the graph, its space being taken over by turquoise.
