Optical illusions That Will Blow Your Mind

#1 Color Cube Illusion

Take a good look at this cube made of smaller cubes and guess how many colors it has got? Don't rush. You can take your time before scrolling down.

#2

Most people would say there are seven colors. White, yellow, green, blue, red, brown and orange. But in fact, it's an optical illusion. The brown square at the top middle and the orange in the front middle are the same color.

#3 Look!!

In reality, they're actually the same color.

This is not a photography trick. It all depends on the context in which you see the color. Our brain sees the shadowy part of the cube and registers that shadows make things darker. So to compensate, our brain interprets the square as being lighter until the shadow is removed.

#4 The Glowing Core

This animated picture has an interesting effect. At first sight, you can only see two colors ignoring the white dot in the middle and it's true that there are two colors. But if Look into the center point and stare for a while, you'll actually see three different colors. A purplish circle and the 4 rotating ‘wings’ are tinted green. But it is just an illusion.

#5 Stare At The Dot

This Picture shows us a part of orange rectangle on the grey background. Also there is a grey strip going up and down. Now, if you concentrate on the black spot in the lower right corner, the moving stripe will turn blue.

#6 The Penrose Triangle

This is the Penrose triangle. One of the main impossible figures also known as Impossible Tribar. When you look at it, it seems that such object can't exist in reality.

#7

Now take a look at how it all works.

#8 Ponzo Illusion

Here is a picture of a street. There are three cars on the road way.

#9

It looks like these cars are different in size. But this is not true. In fact, they are all the same size. It is an example of Ponzo Illusion. The Italian psychologist Mario Ponzo suggested that the human mind always judges an object's size based on its background.

#10

For example, there are two identical objects and one of them looks bigger than it's simply due to the background.

#11 Floating Rectangle

These opposing blue lines look like they are moving simultaneously but it all changes when we cover them with those green squares turning them into a solid blue square.

#12

Here is another example. What is really going on here? What you see at first is a floating shape whose corners are covered with yellow post-its. Your brain immediately recognizes it as a rectangle, as it tries to connect the shape with something already familiar. But see what happens when the yellow stickers are removed from the animation. The actual shape of the floating object is revealed – in reality resembling nothing close to the rectangle you thought you were seeing at first. This is amazing.

#13 Creepy Shadow Chair Design

Those who like unusual objects will be interested in this chair designed by Chris Duffy. It looks like two-legged seats, seemingly supported by nothing at all, but when you sit on it you'll realise its totally fine. In fact, what appears to be its shadow is actually its main support.

#14 Can You See The Yellow Dots?

Next, we have blue rotating crosses and three yellow dots. Now, look at the flashing green dot in the middle for a few seconds. You'll notice how those yellow dots occasionally disappear. In true they are still there. It's just when objects remain in place and they are surrounded by constantly changing figures, they disappear from our consciousness. This interesting phenomenon is known as Troxler fading or Motion-induced blindness.

#15 Which way is the train going?

In which direction does this train move? From which end of the tunnel is it arriving from? It might be both! Check if you can “see” a different direction each time you look at it? If you stare long enough, you might even make the train change its course.

#16 Cement Block Illusion

These pillars are just 3D painting.

#17 Spinning Dancer

Do you see the dancer turning clockwise or anti-clockwise?

#18 Solution

It is not a brain test. Instead, it is simply an optical illusion called a reversible, or ambiguous, image.

The silhouette image of the spinning dancer doesn’t have any depth cues. As a result, your eyes will sometimes see the dancer standing on her left leg and spinning to the right. And sometimes they will perceive her as standing on her right leg and spinning to the left. Most people, if they stare at the image long enough, will eventually see her turn both ways.

#19 Negative Image Illusion

Look carefully at this image – specifically the dots on the woman’s nose.

After 15 seconds, glance quickly at the white space immediately next to her.
