The color of the dress is blue with black. Punto. And has confirmed the British brand Roman Originals, which sells in her shop for 50 pounds (about 192,000 pesos).
Yesterday, a picture of a simple dress, which some see gold with white, and blue with black other, turned her around the world, filled headlines, topped lists of the most read articles in digital media and trend turned in social networks.
But what makes some see it from a different other color? Carlos Francisco Fernández, medical adviser TIME, explained that the color does not exist but is only in the brain.
“It is built in the same way that the meanings of words. Without the neural processes not’d be able to understand the colors of things, as we are unable to understand a language we do not know, “he said.
In what concerns the color perception he added Fernandez, the brain processes the shape of objects on one side and the other colors and unifies according to the condition of each individual.
“When the brain has difficulty integrating the signals received by both eyes or if such signs are sufficiently different or confusing and that is what happens with stripes of her dress, the brain resolves the conflict by suppressing the information received by one eye or gives the brightness or contrast that is suitable and best suited to the characteristics of the person and their biological state, “says Fernandez
He added:” The stripes on Yes launch wavelengths that do not offer sharper contrast and brain take the shortcut that is at hand. In that shortcut will see about the golden, some blue, some white. The truth is that without light all look the same: black “
p class =>. “. “The eyes capture photons, or particles of light, which come with different energies. Color vision is a feature that we thank earners in our retina, about 6 million so-called cones, with which we can distinguish different wavelengths of light, “he says.
Our eyes he adds, are designed to perceive a small range of all light, we call visible light, to differentiate it from other types of radiation such as radio waves, microwaves, infrared, ultraviolet, X-rays and gamma rays, for those who need special tools if we observe them.
“Color constancy is a phenomenon of perception indicates that what we see may change depending on the light source with which it illuminated and ambient lighting. For example, if we see an object under a shadow, the brain acts as if he knew there darken objects. Therefore, to compensate for this perceived colors more brilliant than they really are, “says astrophysicist.
In short, the brain makes many assumptions that depend on the context in which we and individual perception of each.
