Unusual black strawberry. Strawberries without red. A psychologist from Japan created a color illusion Description of the Red Mitten variety

A psychologist from Japan created an image of strawberries without the color red to show that color perception tricks the brain - despite the fact that there are no red pixels in the picture, people still see red in it.

Psychology professor Akiyoshi Kitaoka posted on his Twitter a picture in which there is no red color, writes Motherboard. However, people still think they see red because there are strawberries in Kitaoka's photo:

“The strawberries appear red, even though there are no red pixels.”

US neuroscientist Matt Lieberman confirmed that there is no red in the photo:

“There are NO red pixels in this image. Excellent demonstration of color constancy."

Color constancy is a feature of human color perception that allows one to “recreate” missing or altered colors in the brain if he knows what they should be (or is sure that he knows this).

The claim that a person is "making up" the color red by looking at an image has sparked controversy in the comments. The community did not believe the scientists and tried to prove that they wanted to pull off some kind of trick:

“I think I found some red pixels..?”

"574b4f (color code). This color is part of the rose-red shade group.”

“Akiyoshi Kitaoka, you just don’t understand what Jpeg is, there’s a red one here. Jpeg has three channels - red, green, blue. This is where I removed the red channel.”

Other commentators examined the image and still found no red in it:

“I took out some of the reddest colors from the image and placed them on the right.”

“I drew three rectangles (using color swatches) to show the effect.”

But one user provided seemingly indisputable evidence:

“No red in the image? Look what I did to the “autotone” image in Photoshop. Photoshop instantly detects the red color of the original.”

In fact, the human brain colors images from memory, which is why we find red in the strawberries in the photo, Motherboard writes. Due to evolution, we have learned to understand that lighting can change, but the color of the object we are looking at remains unchanged. So, for example, a ripe banana will always seem yellow to us, even if we walk around the premises with it. different lighting from blue to red - we just see yellow banana under normal lighting and take it for granted that it will not change if we change the lighting. The same with strawberries in the photo: the brain sees the saturation of blue in the image and therefore automatically removes its excess, deciding that the strawberry is red.

To prove that people themselves come up with colors in images, Kitaoka showed another photo:

Do you think there's red here? And in the photo with strawberries?

This is not the first photograph of its kind to receive widespread attention.

Japanese psychology professor Akiyoshi Kitaoka, representing Ritsumeikan University, published a photograph in which a red strawberry can be clearly seen, although not a single red pixel is present in the image.

Using various image processing programs, you can actually verify that the “strawberry pixels” themselves appear gray or greenish, but not at all red. As the scientist himself explained, the secret of the illusion is that the entire image has a pronounced bluish tint. Because of this, someone who sees a photograph involuntarily makes a “correction” for the background and begins to perceive various shades of gray as colors “opposite” to this background.

The most “noisy” illusion of this kind can be considered one that appeared on the Internet about two years ago, which seemed to some to be white and gold, and to others blue and black, and some could at first be sure of one of these options, and after some time suspect that the photograph simply changed. In general, the same mechanism of color perception was involved as in the case above, with the correction that in this case different people chose a different “reference point”, perceived as real color and influencing the perception of the image as a whole. In November last year it was published in many ways.

Among others optical illusions, V different time which attracted quite wide attention, we can recall “size changing” and. Also, a similar reaction from many people was caused by photographs that represent an illusion in a slightly different sense of the word - for example, a photograph in which it is difficult to immediately determine how many girls there really are, as well as a photograph in which one of the girls is sitting on the sofa.

Our body sends signals about problems or diseases that we often are not aware of. And the tongue is no exception: its condition can tell a lot about health and its aspects that need to be paid attention to. Special attention.

website shares these important observations with you.

Strawberry red color

This may mean you are lacking vitamins. A shiny, strawberry-red tongue is a sign that your diet is lacking in iron and vitamin B12. Subsequently, the tongue may become smoother due to the fact that most of taste buds will be smoothed out. In severe cases, acute pain may occur when drinking hot liquids or spicy foods. It is recommended to consult a doctor and review your diet.

Black or brown plaque

A brown or black coating on the tongue may look scary, but most often it only indicates poor oral hygiene or smoking, heavy consumption of coffee or black tea. As a result, it may appear bad smell from the mouth and taste abnormalities (difficulty recognizing tastes). First of all, you should give up bad habits that caused plaque, and pay special attention to hygiene: brush not only your teeth, but also your tongue every day.

Extensive white coating

A white coating, reminiscent of cottage cheese in color and consistency, is a sign of a yeast infection or, in other words, candidiasis. This type of plaque occurs when there is an overgrowth of Candida albicans, a yeast that is present in the mouth in small quantities when the human body is healthy. This may be due to long-term use of antibiotics, diabetes, a weakened immune system, or high blood pressure. It is recommended to consult a doctor.

Folds on the tongue

The appearance of folds or wrinkles on the tongue may simply indicate aging (yes, our tongue ages too). Typically, cracks are painless, but poor oral hygiene increases the likelihood of infection. So, a fungal infection can develop directly in the crack and cause severe pain and burning. The problem is solved with the help of special medications. Poorly installed dentures can also cause folds in the tongue.

Small white spots on the tongue

Their appearance may mean that something is irritating the tongue. For example, a tooth that constantly rubs an area of ​​the tongue. But most often these spots are caused by excessive cell growth in people who smoke. Between 5 and 17% of these cells may become precancerous. If the spots do not disappear within a few weeks, it is very important to see a doctor and have all the necessary tests done.

Persistent red damage

Red spots or blisters that don't go away over a long period of time can be a symptom of a very serious condition. They are often associated with tongue cancer. You should consult a doctor immediately.

Burning feeling

It most often occurs in women as a result of severe hormonal changes, especially after menopause. You should consult your doctor about this problem. It may also be caused by incorrectly selected toothpaste: Some people are allergic to the ingredient sodium lauryl sulfate, which makes the paste foam.

Mounds and depressions

This rather rare feature usually does not pose any danger. If you don't experience any pain, then you have nothing to worry about - Everyone's anatomy is just different.

Painful ulcers

The appearance of painful ulcers is stomatitis, a disease that is considered childhood but affects 20% of adults. Ulcers primarily indicate stress and decreased immunity. They usually go away within 2 weeks. In case of longer manifestation of the disease It is recommended to consult a doctor. It is also advisable to have a good rest and take care of your health.

Hello! I heard on TV that black strawberries have appeared in our country. Is it true? Is it possible to grow it in central Russia? Thank you.

In our country, gardeners are accustomed to growing and consuming varieties of this crop that produce red berries. However, today white and other varieties are gradually gaining positions on the plots and plates of summer residents.

He is from America. This is the fruit of the activities of modern breeders. The fruits of this species are large, juicy in appearance and taste. It is a mistake to think that they are very dark in color in the usual sense of the word. No, the fruits have a rich dark red hue. By the time it is fully ripe, it actually looks like black. But the seeds of this strawberry are still rare species just really black.

Sometimes this berry is mistakenly considered to be the Black Swan strawberry variety shown in the photo. These are frost-resistant strawberries, which, by the way, can also be bred.

Bushes do not require rare berries special care in comparison with other varieties. Plant it in fertile soil, of course, not clay or sandy. Moderate watering and loosening are the main care for it. Interestingly, unlike ordinary strawberries, this type over time it does not degenerate, but, on the contrary, its bushes produce more and more new tendrils, producing more and more fruits. So you can safely plant strawberries, popularizing them among gardeners.

Concerning middle zone Russia, then it is quite possible to select and breed this variety. Seeds are sold in all major gardening stores, and can also be ordered online. In America, these berries are very popular due to their taste. They are eaten fresh, in kind, preparing fruit drinks and compotes.

The leaves of the plant are no less popular. Dry them and use them in winter as an additive to tea. This will be a real prevention of ARVI.

Black strawberry is a very interesting and unusual option berries, which is rare. It has special characteristics. Besides, unusual strawberry has good taste parameters that do not go unnoticed during tasting.

When ripe, black strawberries acquire an unusual dark color that is as close to black as possible. It practically does not grow in our area, since a more suitable climate is needed to obtain a high and high-quality harvest. This variety of berry is often called strawberry for its identical characteristics. It belongs to the perennial crops of the pink strawberry family.

Black strawberries are a berry that has an average ripening period; its pulp is quite dense, without emptiness, as is typical for other types. The fruits are relatively large and cone-shaped, not ribbed. Taste characteristics are at a high level. Strawberries have a pleasant aroma, their berries are juicy and sweet. It tolerates transportation well, so in other countries with more suitable climatic conditions it is grown for export.

Black strawberries can be grown easily, but for this it is necessary to create special conditions that will ensure good harvest. You need to successfully select soil that would be favorable for the growth of berries. The most suitable soil was found to be no different high level heaviness and fertility. It is recommended to add a small amount of sand to ordinary soil to create a better structure.

Sowing can be done using a special container. It should be plastic and transparent. The specified container must be prepared. To do this, the bottom is pierced in several places so that air can penetrate into the container.

Additional funds will require film, which is used as a cover. The proposed container must be filled with highly loose soil. Fill so that 2 cm of the container remains unfilled.

Initially, the soil should be dry, then it is watered with a minimum amount of water. But the soil should remain loose.

To achieve this result, you need to shake the moistened soil a little. A film will help with this, which will prevent the soil from spilling out.

At the end of the procedure, the soil in the container should remain loose, and in no case compacted. This is necessary so that the strawberry seeds get into the soil at the desired level. After this, you need to properly plant the seeds in the soil. They should be spread evenly in one layer. Seeds should not be sprinkled with soil on top. Then the film is taken again and the container is covered with it. The container is placed in the refrigerator for 14 days.

Growing technology

After the prepared seeds have survived the winter, the container must be placed in a sunny place, for example on a windowsill. In this case, the film is left in previous position. It is extremely important that the light level is high. If natural conditions do not provide this, then you need to use an artificial light source.

If the soil is very dry, you can sprinkle it with a small amount of water. Usually after 14 days the seeds germinate. As soon as this happens, small holes are made in the film with a needle. Through them it will get into the container required amount air, and the temperature will change.

Strawberries constantly need minimal watering. This is necessary only as needed, and you must constantly monitor the level of soil moisture. This is done through the container and lid. You cannot open the film ahead of time. Watering is most conveniently done using a spray bottle. A large number of condensation indicates that the moisture level in the container is extremely high, and this negatively affects the plants. To stabilize the situation, it is recommended to open the lid for ventilation.

When 3 leaves appear on the plant, it needs to be pruned. In this case, the strawberries need to be watered well. After the bushes have grown a little, they can be planted in open ground.

Black strawberries are characterized by various advantages, which provide a high interest in culture. You can try to grow this variety yourself, but to get a good harvest, you must follow the recommendations of experts. Extraordinary appearance Both adults and children really like the sweetness of strawberries.
