Strawberries without red pixels. Black strawberries: appearance and taste. Remontant strawberry Little Red Riding Hood, reviews from gardeners
Culture
Internet users are divided into two camps, some say they see the red tint of the strawberries in the picture, while others do not.
This image was shared on Twitter by Japanese "experimental psychologist" and psychology professor Akiyoshi Kitaoka.
The photo shows strawberries on a plate, and it looks like the picture was treated with a blue filter to make the strawberries look less red. And yet the red color is not much muted, is it?
In fact, there is not a single red pixel in this image.
Optical illusions and optical illusions
"The strawberry illusion is created using a two-color method. Even though all the pixels in this photo are green-blue, the strawberries appear red," Professor Kitaoka tweeted.
National Eye Institute visual perception specialist Bevil Conway described the image as an example of how our brains adjust the color of the world around us when another color is superimposed on it.
"If you imagine walking down the street under a blue sky, that blueness, in a sense, 'infects' everything you see around you," the professor said.
Light is an electromagnetic wave that can be different lengths(depending on color), frequency and have different speed distribution.
“If you take a red apple and look at the sky under a blue sky, more blue waves will still enter your eye,” he added.
Other Twitter users proved that there is no red in the picture. They isolated some colors that appeared to be red and looked at them against a white background. As a result, they saw only shades of gray and blue.
Pictures with optical illusions
This is not the first illusion presented by the Japanese professor. Here's another optical illusion where flower-like shapes appear to expand in size as you look at them.
And in this illusion, the circles appear to be spinning left and right when you look at them.
Social networks were “blown up” by a new optical illusion that promises to outshine - a blue-black or white-gold dress, dividing the entire global Internet into two camps, leading fierce debates about the color of the outfit. The author of the new “riddle” was psychology professor Akiyoshi Kitaoka from Japan’s Ritsumeikan University, who showed a photo of a cake with red strawberries, explaining the theory of color constancy. A snapshot of the optical illusion was posted on Twitter by University of California neuroscientist Matt Lieberman, asking followers to indicate what color the strawberry was.

Most subscribers said that the strawberries were red, but it turned out that there were absolutely no red pixels in the photo, and the strawberries were actually gray. Nevertheless, Internet users are perplexed as to how he could gray it will turn out red and asked the neurobiologist to explain the origin of the optical illusion, which has again become the subject of serious controversy.
Later, one Twitter user analyzed the photo with the gray-red strawberries and demonstrated that there are indeed no red pixels in the picture. He explained that the human brain balances White color, but as soon as it sees a blue tint, it automatically shifts all colors in the opposite direction. He also pointed out that the blue component is already contained in the light source under which the viewer looks at the strawberry, and therefore automatically subtracts it from each pixel.

First, without looking under the cat, decide - what color is the strawberry in the photo? Bolder)). The fact is that this is another optical problem - an illusion from Japanese psychology professor Akioshi Kitaoko. All of his works become canonical, and it amazes me every time. But first, Internet users are actively discussing it. This time he asked everyone to guess the color of the berries shown in the picture.
At first glance, this is just a photo 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.
IN different lighting things and colors look different - for example, under office fluorescent lamps daylight or in the soft lighting of the 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 is saying, 'The light source I'm seeing these strawberries in is adding some blue to them, so I'm going to automatically remove the blue component from every pixel,'" color vision expert Bevil Conway explains to 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 White background.Carson Mell/Twitter Copyright holder illustrations by CARSON MELL/TWITTER
Image caption
“I took some of the flowers that seemed to be the reddest parts of the strawberries and layered them on the white background on the right.”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 remember how in 2015 the Internet was divided into two camps, fiercely arguing among themselves what color the dress was: blue-black or white-gold.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.
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.
Strawberries Red MittenRemontant 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

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.
