What if I told you this view isn’t what it looks like? Okay, I’m going to do it... from today I want to upset your most intimate beliefs about the world that we perceive and I want to do it starting with colors.

Are you ready? 

Hold on... the colors are only in our heads. 

Yeah... they’re brain processing, or if we want to be more brutal, they’re his own invention.

Light is composed of photons that we can imagine as particles that produce an electric and magnetic field and therefore not visible.

In our daily experience, in fact, who has ever seen a magnetic field or an electrical impulse in a direct way?

Everything we see in the world is due to photons that are reflected by various objects and that end up hitting our retina.

Here, they stimulate electrical signals that starting from the photosensitive cells of the eyes, after traveling through a long series of neural connections, reach the occipital lobe, in the back of our brain. 

And here "magic" takes place. 

Those electrical signals with specific energies (or if you prefer specific vibrations or if you still prefer specific frequencies) are interpreted by the brain and each of them is associated with a specific color. 

Those colors, however, are not in the world out there, but only in our heads! 

If you think about it, there are animals that receive the same electrical impulse from an object. The same object that our eyes observe. However, they see it in a completely different way as a gray gradation or something, because their brain treats this pulse differently from us.

Color, as we perceive it, is therefore the psychophysical reaction that our brain puts in place when it is reached by an electrical impulse stimulated by the cells of our eyes affected by the deteminate frequencies of light.

To summarize, our brain uses electrical impulses to create a colourful scene that we will use to interpret the world.

We see with our brains, not with our eyes!

Isn’t this all wonderful?
