The hottest topic in the past 24 hours in the world is definitely nothing more than the terrible amount of controversy surrounding the magic dress "Black Blue - White Gold".

In fact, the dress image is a visual illusion in physics . However, in terms of difficulty, the dress is nothing with the classic illusion below. Why? By simply looking at the pictures below, 100% of you will be "troll".

Here are the illusions you will surely be tricked into looking at:

1. Illusion of two puppies

Guess what color the two dogs are?

An uncle is gray-green, a yellow-gray uncle
Both uncle are blue-gray
Both uncle are gray-yellow
Both uncle are gray

If you choose the answer "a gray-green uncle, a yellow-gray uncle" , congratulations, you are in the top of those who have been . cheated. Why? In fact, the two puppies in the picture have the same gray color. However, because the background of the yellow painting turns green, it creates a certain contrast, making your eyes undetectable.

This visual illusion is called Munker , named after the scientist who created them in the 1970s.

2. "Green or gray" illusion

Focused on the black dot and replied, "What color is the mobile rectangle?"

Grey
Blue
Gray blue border
It is indistinguishable because of both colors

If you follow the instructions correctly, you will see the rectangle change from gray to blue after just a few seconds of observation.

The cause lies in the regulation of the activity of visual cells in the retina. According to experts, the opposite colors in the picture will make many visual cells overwork.

Therefore, when observing focusing on black dots for a long time, they become "tired", leading to dysfunction and consequently the color of the rectangle is changed dramatically.

3. Illusion of chess sets

Guess the colors of the above two chess sets?

A black set, a white set
Both sets are gray

Most of us looking at the image above will have a feeling that a set of white flags (above) and a set of black flags (below). But in fact, the pieces in the picture with the same color are gray.

Similar to the first illusion, the color of the chess set is not really different, but our brains are fooled by the background.

With the above set of flags, the background is very dark, so due to the contrast effect, the colors of the pieces light up remarkably. While the lower half has a fairly light background, the opposite effect is to sink the true color of the chess set.

4. Illusion "magic rotation"

Focus on looking at the plus sign and saying: "What color are the dots?"

Pink
Grey
Green

This is one of the classic hallucinations but always gets interesting for many people

Similar to the "green or gray" illusion, focusing your gaze on the black sign in the center of the circle quickly causes the eye to "stun". And after about 10 seconds, you start to feel that the circle moves very fast and suddenly turns green.

Don't torment yourself because when you click on the results, you will see many people being fooled like you!

5. "twisted figure" illusion

What do you see in the picture above?

White center square, cream-colored outline
Cream-colored square, white border
The center square and the outline are all white

If you own superhuman eyes, you will choose the third answer. However, 99% will see white rectangle and cream-colored outline.

This illusion is based on an effect called "Watercolor" that was first described by Baingio Pinna in 1978 in Italy. Accordingly, the outer outline square is covered by two orange twisting lines. This two-way color fades and stains the cream-colored outline, when in fact they are the same white color as the small square in the center.

To verify, cover the outline of the center square. Then, will you see the cream color disappear?
