Strawberry black and white. Red or not? A new strawberry illusion has taken the internet by storm, just like the famous dress did two years ago. Optical illusions and optical illusions

This photo of strawberry cake is being actively discussed on the Internet. At first glance, nothing special: just a photo of poor quality - perhaps the author went too far with the filters.

In reality, everything is somewhat more complicated: there are no red pixels in the picture, but despite this, the human eye still sees red berries. The red color of strawberries exists only in our imagination: the mind deceives us because the berries are depicted on a blue background.

Things and colors look different in different lighting - for example, under office fluorescent lamps daylight or in the soft lighting of the living room. However, the human brain independently makes changes to the drawing so that we still see the strawberries as red.

This feature of human perception is called “color constancy.”

"Your brain says, 'The light source in which I see these strawberries is adding some blue to them, so I'll automatically remove the blue component from every pixel,'" explains the color vision expert. Bevil Conway in an interview with Motherboard.

Of course, we know that strawberries should be red. And it also helps the mind to correct the color of the image.

Then I joined the discussion Matt Lieberman, posting on Twitter a slightly modified picture, which, however, also did not contain red pixels.

Many responded to Matt's post by adding gray rectangles to his picture for comparison. Carson Mall took color samples from several places that appear red to us and placed them on White background.

Grey colour becomes more obvious if you look at each berry separately from the rest of the picture. Try covering the background in the photo with your hands.

In 2015, the Internet was divided into two camps, furiously arguing among themselves what color the dress was: blue-black or white-gold.

Gray strawberries that look red have a slightly different explanation, but in both cases we are talking about color correction, which our mind resorts to depending on the type of lighting.

Strawberries Red Mitten

Remontant strawberry Little Red Riding Hood and Little Red Mitten are similar hybrid varieties. They have a compact bush structure and fruits with a pleasant taste and smell. They are characterized by excellent yield and rapid ripening.

Description of the Red Mitten variety

Little Red Riding Hood, like Little Red Mitten, was obtained by crossing two crops (strawberries and strawberries) at the VNIIR breeding station in Crimea. These are productive varieties of large-fruited strawberries that bear fruit abundantly in southern latitudes from June until the first frost.

At proper landing 8-10 large white flowers are formed on each peduncle. Strawberry Red Mitten, reviews of which are filled with admiration for the taste and aroma of the berries, has an oblong, elongated shape, and the “cap” is oval. The fruits of both varieties are large, each weighing up to 35 grams.

Due to their relative resistance to disease, hybrids do not require special care. The bush grows powerful, densely leafy, semi-spreading. There is an average number of rosettes and green antennae of average thickness.

Both varieties can be grown as pot culture. These are relatively new hybrids, but have already gained recognition among experienced gardeners. The increased interest is caused by the excellent quality and presentation of the ripened fruits.

Experienced summer residents They note that the berries of the Red Mitten are slightly sour, but they begin to bloom and bear fruit faster. More resistant to frost and excess moisture.

Rules for planting and growing

Red mitten - strawberries that have collected a lot positive feedback. But to get the ideal harvest, you must comply with the growing conditions.

It is recommended to sow in a special container. To get a good result, you should use fertile, soft soil. Planting is best done in March and April. It is important to distribute the seeds evenly into pre-moistened soil. For the best effect, the planting should be covered with film until sprouts appear.

To speed up germination, it is necessary to regularly water the soil and observe temperature regime in room. For good development, it is recommended to use nutritional supplements.

The appearance of 2 leaves on the seedlings means that the seedlings can be picked and planted in pots. If there are 6 true leaves, the plants are ready for open ground.

Before boarding open ground shoots need to be acclimatized to permanent place. Only strong plants are chosen for planting. It is important to maintain a row spacing of 30-35 cm, and the gap between bushes should vary between 17-20 cm.

Strawberry Red Mitten - reviews from gardeners

Gardeners fully confirm the declared characteristics of the crop. The plant ripens early, practically does not get sick, provided that the planting rules are followed.

"Red Mitten strawberries amazed me. In addition to the ideal taste, I discovered additional advantages of the variety - excellent transportability and keeping quality."

Irina, 37 years old, Moscow

“Ripe berries have elastic skin and dense pulp. I am happy to grow the crop for sale and for my family.”

Alexander Petrovich, 48 years old, Perm

“The first time I grew Little Red Riding Hood was not successful, I read little about it, and did not know the specifics of planting and care. This is very important! I did everything according to technology, and the result was not long in coming, the yield is amazing!”

Kirill, 39 years old, Chelyabinsk

Remontant strawberry Little Red Riding Hood, reviews from gardeners

Strawberries Little Red Riding Hood, reviews of which are often left by gardeners from the Moscow region, are excellent for growing in middle lane Russia. The fruits are used to prepare compotes, desserts, juices and frozen for the winter.

“Last year we took Little Red Riding Hood for sowing, I really liked the strawberries: they are not fussy, the germination rate of the seeds is 100%. The berries have marketable condition, pleasant aroma and delicate taste."

Maria Ivanovna, 56 years old, Rostov-on-Don

“We heard a lot about the strawberry varieties Red Riding Hood and Red Mitten, the reviews were mostly positive, so we took both varieties at once. They are very similar, they sprout together, grow the same. We noticed that the taste of the berries of the “Red Riding Hood” is sweeter, so we gave preference to it. "

Ilya Sergeevich, 64 years old, Moscow

“It’s a very picky berry, I’ve tried many remontant varieties of strawberries, but Little Red Riding Hood requires special care. Otherwise, germination is poor and the harvest is so-so. I liked the taste, it’s reminiscent of strawberries, the berry is juicy, the seeds are not hard.”

Natalya Andreevna, 87 years old, Kislovodsk

Bottom line

The strawberry variety Red Riding Hood meets the basic requirements for crops in this category. A powerful but compact bush is ideal for planting on small areas. By planting plants on time, you can harvest tasty and healthy berries until deep frost.

This photo of strawberry cake is being actively discussed on the Internet. Why?

At first glance, this is just a picture of poor quality - perhaps the author went too far with the filters.

In fact, everything is somewhat more complicated: the fact is that there are no red pixels in the picture - which does not prevent us from seeing red berries.

The red color of strawberries exists only in our imagination: our reason deceives us, since the berries are depicted on a blue background.

Things and colors look different in different lighting - for example, under office fluorescent fluorescent lamps or in the soft lighting of a living room.

However, our brain independently makes corrections to the image so that we still see strawberries as red, regardless of where and under what circumstances we eat them.

This feature of human perception is called “color constancy”.

"Your brain says, 'The light source in which I see these strawberries is adding some blue to them, so I'll automatically remove the blue component from every pixel,'" explains color vision expert Bevil Conway in an interview with Motherboard.

"And when you take the gray pixels and remove the blue, the result is that the image appears red to you," Conway explains.

Of course, we know that strawberries should be red. And it also helps the mind to correct the color of the image.

Matt Lieberman then joined the discussion by tweeting a slightly modified image, which, however, also did not contain red pixels.

Many responded to Matt's post by adding gray rectangles to his picture for comparison. Carson Mall took color samples from several places that appear red to us and placed them on a white background.

The gray color becomes more obvious if you look at each berry separately from the rest of the picture (for example, by covering the background of the photo with your hands).

Many people remember how in 2015 the Internet was divided into two camps, fiercely arguing among themselves.

The red-looking gray strawberries have a slightly different explanation, but in both cases we are talking about color correction, which our mind resorts to depending on the type of lighting.

Optical illusion with strawberries. To the observer, the strawberries, as expected, appear red. But in reality there are no red pixels in the photo.

For those who don't believe, here's the proof: the right side shows the "reddest" colors in the image.

The photo with the strawberries appeared exactly two years after the dress, which seemed white and gold to some people, and black and blue to others. The basis of such illusions is the same property of the brain.

The fact is that lighting conditions greatly distort color scheme the object we are looking at. However, our brain has learned to “compensate” for these distortions, so we see strawberries as red under all conditions. The same thing happens in Kitaoka’s photograph - the brain “corrected” the colors, removing blue shades.

From the photograph with the dress it was not clear in what lighting it was taken, so different people“corrected” colors in different ways. In the case of strawberries, its presence in the frame helps us a lot - we know that strawberries are red.

And here is the ill-fated dress, over which lovers quarreled and best friends. After the puzzle was explained, the popularity of this dress model increased greatly. In America they sold an amazing Halloween costume - famous dress, half of which was black and blue and the other white and gold.


About a year later, Buzzfeed editors found another puzzle for their users. Most users thought it was in one hand blue pill, and in the other - red. In fact they are both grey. So our brain is very easy to fool.

Buzzfeed

  • David Duchovny, who played a womanizer writer in Californication and an FBI special agent in The X-Files, notified the world that he thinks the dress is green and blue.
  • The photo with the strawberries was published exactly two years after the ill-fated dress.

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:

https://twitter.com/carsonmell/status/836411673552400384?ref_src=twsrc%5Etfw

“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:

https://twitter.com/EdwinNikkels/status/836922568279982080

“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?
