Also, seeing how I have one of the oldest profiles on ATS wouldn't it stand to reason that I was probably closer to adolescence at the time of
creation of my profile?
No offence, Masta, but as you are a long term member,
hasn't all this been discussed many times on ATS?
My point is that these seem like banal, adolescent questions.
The eye assigns colour to a range of light wavelengths
that may not correspond with the colour of the wavelength itself.
We have cones in the eye which detect red, green, and yellow.
But we only detect light and colour with our eyes. (Imagine a camera lens and a CCD chip)
What we percieve
is processed by our brains in a similar way to how computers process Holograms.
The brain learns which colours are which and uses this information to process visual information,
as it does with acoustic and sensory information.
Only smells are transported directly to the brain, otherwise its in a black, sealed room,
with no contact to the outside world except the electrical signals which it processes.
The world we see is made of light. How we see it depends on how the light reaches our eyes.
The sky is blue because blue frequency light is scattered by Nitrogen and oxygen molecules (Air) more than lower frequencies. Our eyes dont pick up
indigo or violet very well unless it is directed, so the sky looks like a mixture of all light frequencies (white) and Blue, so it's Light blue.
The sun is yellow because yellow is the median colour in our visible light spectrum. It looks red when the sun is low, as light is scattered more and
more by dust and water vapour in the lower atmosphere (air).
The tomato looks red, because the pigment "lycopene" absorbs green and blue frequencies, but reflects red light..
A leaf is green because "chlorophyll" absorbs red and blue frequencies and reflects green light.
Your favorite crayon is red because the dye in the crayon absorbs or scatters all other frequencies of light.
It is red because light (in the red bit of the spectrum of visible light) is reflected towards your eyes
Change the colour of the light source and you change the colour of the Crayon.
Every one percieves the world around them from inside a black box of sensory information.
The whole world is inside your head, an interactive personal holographic reality.
Everyones eyes have different amounts of each type of cone receptor, yet everyone, given similar circumstances percieves the world of colour exactly
the same. You "see" with your brain, not with your eyes.
You see with your brain
That's why your favorite Crayon is Red.
