Ok, another unanswerable question

[Not]

About a year ago they discovered a new shade of black that absorbs something like 97% of all light, where-as normal "black" absorbs something like 93%. :P

 

 

 

Black isn't a color.

Thats why he called it a shade :lol: (I think)

 

And I think that what we call black is just a really dark colour, black cannot be seen because it reflects no light at all.

how do you know that the colour you see is the same as what other see? what if when you see blue, you see what most people would call green?

colour is simply our nerves reacting to electrons. if they want to see colour, get a tooth pick and poke around in their eye, they will all of a sudden see colour (although the pain might make them not care very much)

Because we know enough about the physiology of the eye and the brain to know that what everyone sees is more or less similar.

 

 

 

Color-blind people though, interestingly, lack the receptors required to see certain primary colors of light, or are deficient in those receptors. The most common one I beleive is green-blind. They see green as sort of a light-red pinkish color...

Actually there are colors that may not be visible to the eye or scientific equipment. Color, or images, being trasmitted thourgh space take trillions of years to reach us. The possiblity of another existence could possibly mean new colours.

 

 

 

Thats clever, considering the universe is only 13 billion years old...

 

 

 

Our eyes cannot pick up color that isn't in the visible spectrum.

 

 

 

Way to state the obvious =D> If we couldn't see it, we wouldn't call it the visible spectrum.

 

 

 

Visible light is just a fraction of the electromagnetic spectrum. The red end of your visible spectrum has a wavelength of around 700 billionths of a metre, while the blue end is around 400 billionths of a metre from peak to peak. Human eyes can actually only respond to three different wavelengths of light, Blue, green and red. If yellow light falls on our eyes, the wavelength stimulates both the Green and the Red receptors a little each, and thus we see yellow light. The colour we see them as is simply our perception, and it is how we detect them.

 

 

 

Things like Radio waves, X-rays, gamma-rays and the like are all on the electromagnetic spectrum. If we had organs that could detect them, then they might appear to have a colour. Colours are simply how we tell one wavelength from another, within our visible spectrum.

 

 

 

Now, I have said before the 'Human visible spectrum'. This is because some animals can see wavelengths that we cannot. For example, Boa constrictors can sense Infrared light. We can to some extent, but we detect it as heat, which is not exactly an efficient of descript way of percieving it. However, Constrictors can see infrared, so if you were to put a Boa Constrictor in a room that was completely dark, but had say, a burglar alarm motion sensor in it, the snake would be able to 'see' its way around. In the same way, Birds and bees can 'see' ultraviolet light, we cannot. Many flowers have ultraviolet patterns on them, which bees can see, and so that is how bees know which flowers to go to.

 

 

 

My point in this post is to show that there is no way to explain to someone what light or colour is if they were born blind. If you can find a way to explain to someone what ultraviolet 'looks' like, then you can find a way to explain to a blind person what a colour is. However, to a blind person, they do not have a visible Spectrum, and they cannot detect any part of the electromagnetic spectrum at all, so it is impossible to do this.

 

 

 

If you read this far, congrats, and thanks! I hope I made some of you think a little bit :P
