I did not copy the entire article, though interesting. But, this is all the proof I need that Miss Diamond could not possibly have favored yellow over all others  |
She could have favoured "yellow", just to her it actually looks grey
"Dogs do in fact see "in color", as shown by the fact that a dog's eye contains both rods (which we associate with B/W vision) and cones (which differentiate between colors). While humans' cones are attached to neurons that react to light at 435nm, 545nm and 570nm, a dog's cones react at 429nm and 555nm. This means that a dog sees somewhat as does a human with red-green color blindness.
This means, for instance, that what a human perceives as red, a dog probably perceives as green, and what a human perceives as yellow, a dog sees as a nuetral color -- gray.
Canine eyes also lack another human trait: the fovea, an area especially dense with detail-sensing cells. As a result, their detail vision is not as good as ours. But they make up for this by having much better night vision and greater sensitivity to movement."
