Do Colors Really Exist in Nature? Or Just an illusion of our Brain!

Do Colors really exist in nature or are they just an illusion with which our brain fools us into believing that colors actually exist in nature?

So, let's think about it for a while and see if we can figure out what shades they are. Imagine you're on a deserted island with no red, and you have someone with you who can see red and has seen it before, but no one has ever taught him it's called red. He sees the color with his eyes but doesn't know what it's called, so you told him that on Valentine's Day, the beloved gives his beloved a red heart as a symbol of their love, then he asked you what the meaning of the red color and how this color looks?... Will you be able to describe to him the significance of the color red, as well as the fact That red is the color he already saw but did not notice its name?

You can't, of course, because the colors have a connection to emotion and thinking and if had nobody told him before the color was called red, he would never know it.

We know also that light is required if things are to be seen in nature, since the light acts as a mirror that sends information from the environment where things are placed into our eyes, and the eye sends this information directly into our brain. The light in the form of signals shines on objects and transfers pictures to us in real-time, and when there is no light vision stops, as the channel transferring images of things to us temporarily doesn't work.

A limited portion of the overall electromagnetic spectrum of nature is only sensitive to the human eye. The wavelength of this small spectrum called Light is between [400nm and 760nm]. Every spectrum above this area is not sensitive to the human eye and its cause is purely biological and is connected with the components of the human eye.

This visible spectrum or "light" is the only one that the human eye can sense, just as we see it in the form of different colors from red to violet, and to know what is the reason for our vision of these colors and their source, we will present three possibilities:

1. The first possibility: this apparent electromagnetic spectrum, i.e. light, has colors, and the eye does nothing more than it shows and sees it.
2. The second possibility: is that everything in nature has inherent colors, and the light represents not more than these elements and makes the eye see them in color.
3. The third possibility: These colors are not a property of light or objects, but an illusion that comes from our perception of the environment, which is why the brain uses these tricks to distinguish things from nature in vision.

The first and second possibilities refute each other for if light has the property of color as an inherent property, then nature does not have colors because this light gives these things color when it is reflected on them. After all, if colors are an inherent property of things in nature and not a property of light, then why do we see colors when we look directly at the light?  such as light from the sun, for example, or the light emitted by a laser device.

But even so, matter and electromagnetic rays cannot be separated in any case since they are almost two things that are related in the first place, since the rays from the sun and stars originate from matter, and the fusion reactions that occur between chemical elements such as hydrogen within the stars are the ones that emit that energy in the form of electromagnetic waves. At many wavelengths, like the visual range, where the human eye is capable of observing.

And the third option remains the most possible since a human can see colors even in the absence of light. For example, as we sleep and begin dreaming, we see the world in dreams in the same way we see it in reality in color, and we can close our eyes in the dark when completely awake and imagining colored objects. After all, this shows that colors are a creation of our minds, that they do not exist in nature, and that they have nothing to do with visible light.

Indeed, research in biology confirms that colors are only found in the human mind, as the retina of the human eye consists of two types of light-sensitive cells:

Rod cells are photoreceptor cells of the eye that are located at the retina's outer edges. In low-light situations, rod cells are responsible for vision.

Cone cells are the second type of photoreceptor cell in the eye, and they are located in the retina's fovea. Cone cells are responsible for color perception and vision under bright light.

Cone Cells detect the majority of the visible spectrum wavelengths of light, such as yellow, green, and brown... but to varying degrees, with all cone cells operating in differing degrees according to the frequencies, causing the mind to imagine the rest of the colors for us.

These cone cells are responsible for the vision and decide which colors your brain can make you see, because our sense of colors in this environment is dependent on them, and in the absence of any visible spectrum frequency, the brain will make you see black, indicating that there is no signal coming from the cells.

The question now is who decides what kind of rays are reflected by objects in nature, causing them to appear in the color we see them in?

The type of rays that will be reflected and dispersed in all of the surrounding space is determined by the atomic and molecular structure of natural objects. As frequencies reflected from these objects reach your eyes and activate the conical cells, you can see colors that correspond to the form of frequencies detected.

Simply, As light is scattered on a specific object, the eye picks up the wavelengths, sends a signal to the brain, and the brain converts the signal into specific colors.

Conclusion

The universe we see in color is just created by our minds and is a result of our perception of nature only.  Few animals have more than three types of cone cells, allowing them to sense frequencies that we cannot. Take the goldfish, for example, which has four types of conical cells, each of which can sense ultraviolet rays. We have no idea of knowing which color he sees at this frequency, so his world of colors would be very different from ours.

For eg, a person's eye does not have cone cells for detecting the frequency of the yellow color, so if he sheds the frequency of red and the frequency of green at the same time, he will see them as one color, which is yellow, and if he shed the red, blue, and green at the same time, he will see white, and if his eye does not obtain any Hesitation, he will see black, and so on...Backing to goldfish,  We don't know what this fish sees or how his universe of colors feels whether he sees red and ultraviolet rays at the same time because we've never seen what ultraviolet frequencies look like..

Colors are biochemical phenomena, not physical ones, and they have little to do with optics because they are related to the nature of the eye sensors and vary from one object to the next depending on the components of the eyes. As a result, each organism has its own universe of colors based on the kind of cone cells it has.

The universe we see and experience, which we believe to be the true reality that our senses and minds cannot deceive us about, is really nothing more than an illusion. Truth, on the other hand, is not like this; nature and matter are true entities that exist outside of us, but the representation we see and the way we view them are not.

Note:

There is no difference between a white person and a black person because black is only found in your brain!
