Optical illusion with colors

Our way of seeing things is very relative, so much so that we would never have imagined what our human eye is capable of when we have a simple image in front of us. It is for this reason that there have been many psychological or physical aspects that have been taken into account, whenever we have tried to analyze a particular graphic element.

But the truth is that there are a series of images designed in color, which are capable of sending messages to our brain, so that our eye deceives us and can create a series of optical illusions.

Yes, we have already deciphered the subject of this post, so if you are still curious to know how this type of illusion is created in our minds, You can not miss all the information that follows.

Optical illusions: what are they?

An optical illusion is defined as a type of mechanism or system that serves to deceive the visual system that we humans have. This system is a chain that goes from the eye to the brain, so that our mind and our vision, they are able to perceive or project an image and read it in such a way that it is distorted or with a certain movement.

These optical illusions can appear naturally even in the environment in which we find ourselves, or they can be designed from a simple image that is presented to us. For example, our brain can trick us in such a way that our eye can only perceive a small amount of the information displayed on an image.

It is for this reason that it is very curious how our mind can get to exchange information with our vision, and in this way manipulate it without us noticing, this is the true logic and objective of optical illusions.

Types of optical illusions

physiological

They are also known as the afterimages, and it refers to those images that are kept alive in our mind. For example, this is what happens if we look at an object that has a large amount of luminosity. Our brain is capable of maintaining this type of mental bell and even creating great visual stimuli.

Cognitive

Cognitive illusions are illusions that are created through different experiments that are performed. For example, it is the case of the figures that we observe at a certain moment, which appear to change their shape and similarity on large scales.

Types of illusions with colors

colored dogs

There is an experiment where a silhouette of dogs is drawn on some cards. By moving these cards, our mind makes our eyes believe that dogs change color constantly. But, the truth is that the three cards have the same color. 

This experiment was designed based on color theory, that is, how color can affect in a certain way our vision of the different tones that are created by combining the three colors, which, apparently, are exactly the same.

The repairman of a telephone line

In this experiment, we have to try to observe and fix our vision on a central point that appears in the image. Without us noticing, the image will change and the color will remain the same, even though the image has changed to black and white.

It is undoubtedly one of the best experiments that have been designed, where in addition to testing our vision and our mind, we can also be able to deceive our eyes without realizing it.

the gray bar

The gray bar is another of the experiments that has also had a great impact, if we talk about optical illusions. For this experiment or test, we must focus our eyes on a black point for a few minutes.

The point can be found in one of the lower parts of the test. In this way, we can see how the bar that moves from top to bottom changes its tonality. 

Without a doubt, it is another of the experiments that has attracted the most public attention, since in this way, we can see how our mind is capable of deceiving us once again.

the famous dress

A few years ago a photo went viral where two dresses appeared that, apparently, were exactly the same. The only difference was that at a glance, a percentage of the public saw it blue and the other percentage saw it gold. 

The truth is that both dresses were the same color, but our mind and our vision were capable of interpreting a tertiary color. That's how this experiment kept thousands and thousands of people awake.

It is another of the reasons that demonstrate how our mind and vision are capable of going further.
