Does color exist, or does is it a product of the brain?

Question

I know this is similar to "if a tree falls in a forest...", but I'm curious whether color is a subjective experience, or whether different wavelengths have "color" as an attribute.

Hope I worded this correctly...

Answer 1

Color plays a vitally important role in the world in which we live. Color can sway thinking, change actions, and cause reactions. It can irritate or soothe your eyes, raise your blood pressure or suppress your appetite.

When used in the right ways, color can save on energy consumption. When used in the wrong ways, color can contribute to global pollution.

As a powerful form of communication, color is irreplaceable. Red means "stop" and green means "go." Traffic lights send this universal message. Likewise, the colors used for a product, web site, business card, or logo cause powerful reactions.

Color Matters: Color & Vision: How the Eye Sees Color

Color originates in light. Sunlight, as we perceive it, is colorless. In reality, a rainbow is testimony to the fact that all the colors of the spectrum are present in white light. As illustrated in the diagram below, light goes from the source (the sun) to the object (the apple), and finally to the detector (the eye and brain).
1. All the" invisible" colors of sunlight shine on the apple.

2. The surface of a red apple absorbs all the colored light rays, except for those corresponding to red, and reflects this color to the human eye.

3. The eye receives the reflected red light and sends a message to the brain.

The most technically accurate definition of color is:
"Color is the visual effect that is caused by the spectral composition of the light emitted, transmitted, or reflected by objects."

Answer 2

Does Color Exist

Answer 3

You know, I always argued that scientist may be wrong about how we see color as we do. But a mental processes and all that I can agree to. Remember too that light energy can be separated via a prism and that's why there are colors through light.

Here's what I see: an object with certain texture or surface has the ability to absorb or reflect light energy. I wonder if you understand the rainbow colors and all that. Different light color possesses different wave length.

For an object to properly projects it's true color to a percieved eye the luminance of the the light has to be at an ambient brightness (not too dim or too bright). I truely believe that an object does possess a color that we see. Some how scientists seem to believe that the object you see has no color at all. I don't want to rub you the wrong way now. But I can be wrong as well. Here's what I see, on this subject. I Believe that because any object has it's own true color, it is the light(s) energy that it absorbed and reflected that plays a role in how we percieve color. What we see is a mirror reflection of what's in the open surrounding area, the reflection collected on the lens of our eye, similar to a camera lens. In order for us to process the information our eyes have special light/dark sensor nerves that turned what was reflected on our lens into significant informations and send that informations (raw unprocessed information) to our brain to be processed. Our brain has no special trickery that could turn the object we see into color by utilizing the different energy of light or it's different wavelength into the color we see. That's what I understood explained by optics specialists. Make sense. Now the informations from your eyes are sent into our brain and going all over the places in our brain. Scientist couldn't pinpoint to just one special area that our brain process colors. They can scan the brain, and see that the back part of the brain is more active for visual but what they also see is that the brain seems to have minute activities all over too.

The concept of color is simply the product of the biological mechanisms for detecting and interpreting a certain part of the electromagnetic radiative spectrum, helping us to distinguish objects. The apparent explanation for this is that color perception helps us distinguish object that may be food, or may present some danger, or for mating. Color does play a documented role in all of those things. In other words, if we didn't perceive colors, our species might not have survived.

Answer 6

True, True, and True! All of this is true. Color is subjective! Wavelength does determine "color," but it is subjective to the person who is experiencing it. Same as the tree falling in the woods, no one cares if it falls when no one hears it. All experience is a product of the brain. Hate, rage, and anger; as well as love, lust and jealousy are all subjective to the person who is the "beholder."

Answer 7

Color is the byproduct of the spectrum of light, as it is reflected or absorbed, as received by the human eye and processed by the human brain

Answer 8

I think most people who see a rainbow will say it has colors in it. The reality of that goes to the brain and we see it.

Answer 9

I believe that color is perceived by the eyes. Another question might be "are there colors which we can't see?"

Answer 10

There must be colors or our brains wouldn't see different ones.
