Aside form our eyes, does anything really have color?

Question

I read our eyes can only see visible light. Color is dictated by which frequency of visible light our eyes are picking up. I also read that objects absorb certain frequencies and are made to emit a specific frequency, the one that gives that respective object's color. Like a red rose for example. It's inherit make-up allows it to emit "red."

I also notice that when there is a absence of light, even the whitest walls in a dark room are black. So, can it be said, that in reality, everything is naturally colorless or black? That when we close our eyes the world around us is just absent of color. Only our eyes make color. You know what I mean?

Answer 1

Your understanding is not quite correct. First of all, color is not an attribute of objects, but is a name given to our sensation of those objects. As well, there is no such thing as an absence of light. That is a physical impossibility. What you must mean is an absence of light within the visible spectrum. The lack of visible light does not affect the color of objects, but only affects our sensation of such objects. The notion that everything is therefore black or colorless is an incorrect interpretation. Most objects on the earth are not sources of light. They only emit light in reaction to absorbed light, where the primary source of light is the sun. Without the sun, there would be no us or anything else on the earth. You recognize rightly that the sensation of the color of an object is dependent upon the amount of light available from a source of light, such as the sun. It is not correct that things are inherently colorless, as color is not a property of objects, but is dependent upon the interpretation of an observer.

Answer 2

Firstly, we must understand that WHITE LIGHT is a mixture of many different wavelengths of light. We can break this into its constituent colors by using a prism. We usually refer to 7 colors in the rainbow, but this is a simplification.

To make matters more complicated our eyes have only three types of color detector. Red, Blue and Green.

If we shine white light on to a green flag, the flag absorbs all of the waves except green, which it reflects, so we see a green flag.

However, the eye and the brain work in tandem to decode what you see. For example, when yellow light hits your eye, it triggers red and green receptors - the brain tells you its yellow.

So that your eye can have some color constancy in varying light conditions, the brain actually compares the whole area you are looking at in order in interpret color.

For instance, if you turn your TV off, you'll see that the screen is a muddy grey color. However, if you watch a penguin on TV its colors are a vivid black and white. So you brain maps "contrasts" rather than absolute color.

I hope this helps!

Answer 3

We see a rose as red because a rose reflects red light, and absorbs other colors. (A red rose, anyway). Since color is a property of which wavelengths of light a surface reflects, you don't get color without light.

"visible" light generally refers to that area of the spectrum that human eyes can see; a different (overlapping) portion is visible to animals.

Answer 4

Do our EYES see color or

Does the BRAIN see color after the nerve impulses reach the other end of the optic nerve?

Does the BRAIN see color or does the MIND see the color?

Does the MIND see color or is it the internal, Silent Witness -- CONSCIOUSNESS (known in eastern philosophy as "ATMAN"), aka: Self (n.b.; capital "S") that sees color?

All is maya! (names and forms)

In western terms we call it PERCEPTION as opposed to reality.

For all I know, what you perceive as RED, I perceive as GREEN and vice-versa. Although our perceptions may be different we can talk about it because we have both given it the same name.

Answer 5

This concept is related with hindu philosophical term Maya ie the whole world is a optical illusion as we perceive it

Answer 6

paperwork, Hypocrisy, and Herd Mentality by way of subjugation with the aid of propaganda and liberal training structures. purely one thing that includes recommendations after analyzing your disposition/question. i think like the reason being this, they are draconian bureaucrats, and what Fox Molder continuously mentioned on the x-documents includes recommendations; they like to do away with, or have not something to do with something that cannot be categorized, categorised, or fairly referenced.

Answer 7

You are 100% correct!
Everything is just an optical illusion.
