However, this preference completely disappeared when there were
interesting things on the screen to look at. In the first situation,
the monkeys had nothing to attend to, but their own sensations.
But in the second situation, where their attention was drawn out
to the external world and away from their own responses,
they had no preferences.
Still, that the monkeys all preferred blue to red strongly suggest
a genetic basis for it.
But the situation can also be understood the other way around.
That is to say, it is our experience of the inner world that confirms
the existence of a person!
Certainly sensations are important to us humans, as is being conscious. We even like consciousness in other people. Certainly, the last thing we want is to be conscious in a world where everybody else are zombies.
Imagine if we didnt have conscious vision. If we werent conscious about seeing red. According to Humphrey: It turns out that in order to see, you must believe that you can see. If you dont believe it - you cant see [p. 45]. You must take part in the construction and sensation of what to see. Otherwise it becomes a reality like blindsight - where a patient believed he was blind, and reported having no visual sensation, and yet he could still guess the shape and positions of objects (later it turned out that he could also accurately guess colors).
About web pages and color themes:So, with both rhesus monkeys and humans in favor it shouldn't be to difficult to pick a background color theme for a homepage... :-)
Even easier considering the symbolic values: Where blue (, ) is the color of the heavens
(dark blue represents knowledge, power, integrity and seriousness).
And where red (,) is the color of the ground (at least in Africa). Symbolicly representing anger, war, sin, guilt, pain, passion and blood.
Guess what color theme I chose for my homepage .... :-)
