How can you prove to a group of blind people that color exists?

Answer 1

The same way you teach an atheist that God exists...

Answer 2

But, actually, color DOES NOT exist. It is a phenomenon... not a 'thing'. Color is entirely a construct of the brain... the method which the brain has evolved to represent certain frequencies in the electromagnetic spectrum.

There are several things involved in 'color':

* The emission spectrum of the illumination source

* The absorption spectrum of the illuminated object(s)

* The absorption spectrum of the detecting instrument (eyeball)

* The sensitivity and linearity of the detecting instrument (eyeball)

• The processing circuitry in the visual cortex

Change any ONE of those things, and the 'color' changes.

With regard to teaching a group of blind people about color... I would think that the only way would have to be by analogy... and the obvious choice would have to be sound.

Answer 3

Color is a construct of our minds. The visual wavelengths of color are detected and processed by our optic nerves. If you do not have functioning optic nerves, i.e. you are blind then color doesn't exist in the same way for you as it does for people who can see. How can you prove that something exists for people who cannot detect it? How can you describe the color Red? People who are blind would ultimately have to accept that color exists on faith it could not be proved to exist in the same way as it can be for someone who sees.

Answer 4

Color doesn't "exist."

Light is a form of radiation, and all creatures who have sight have the ability to detect that radiation in particular ways.

Some need more light radiation to see than others (dogs and cats out-perform humans here). However, our human light collectors (i.e., eyes) are fairly good at picking up the various wavelengths of light as "colors."

If any creature doesn't have sight, it has no need of color. (Blind humans may need some help in choosing clothes whose colors match, but all of that is for the benefit of the sighted clods who look at them, not themselves.)

Otherwise, color to a blind person is irrelevant. By asking the question, you're basically telling a blind person that your perception of the world is superior to their own.

Answer 5

How can you even prove to a group of blind people that sight even exists?

Answer 6

First place their hand on a sheet of colored construction paper and tell them the word for the color of the paper. Then put a different color in front of them doing the same thing. They will 'feel' the different vibrations of the colors and start associating that vibration with that color.

This has been successfully done by Carol Laros years ago. -(probably spelled the last name wrong, sorry)

Answer 7

you can prove they exist if they trust the teacher teaching them ,the real question is how do you show a blind person the nature and beauty of color and light

Answer 8

Color doesn't exist. It is the way our brain interprets different wavelengths of visible light. The "color" of any object we perceive is determined by the wavelength of light that strikes it and the subsequent wavelength of the photon that is emitted (reflected) from that material. If the wavelength of light that strikes the object is changed then the emitted light (photon) wavelength is changed and we interpret that as a different color. All cats are gray in the dark.

Answer 9

Train them to sense the difference in vibrations of colors. It's been done.

Answer 10

proof to them that god is existing first and that he is the creator of every thing then take 2 flowers differ in colours and let them touch it
they will know that you proved that right

for the proof of god i think that it is so simple !!! let them think about any thing even if the fly and how it is living

Answer 11

How can you not accept the deeper message of oblivion that the lack of sight proves.
