Let’s see all the colors in the same way? It is a question that experts have been trying for some time to answer, but so far the science had never given certain results. Now a study published on The Journal of Neuroscience It seems to be able to clear us a little ideas: the vision of the colors is the same for everyone, but what contributes to giving a different nuance (literally) to the colors we see is the experience we feel when we look at something.
Predictable resonances. When we observe something our brain lights up: by giving in front of a magnetic resonance imaging (MRI) we can guess what the color that the person is seeing only by observing the brain regions that have activated are.
Using this technique, a team of researchers subjected 15 people to MRI while observing red, green or yellow -fledged rims; Based on the average response of the brain given by 45 subjects who observed the same colors, they then analyzed the magnetic resonances of the 15 participants, which were the same.
In other words, the colors “light up” in the brain of all the same regions.
The case of “The Dress”. The fact that We see All colors in the same way does not mean that there we perceive In the same way: in fact we know that different people, with a vision of normal color, have different experiences. Do you remember for example the famous case that broke out on social media ten years ago concerning the colors of a dress?
There were those who swore were white and gold, who black and blue (the seconds were right). In this case, the neurons sent everyone similar visual signs about the colors of “The Dress”, but the brain of people interpreted those signals in a different way (a study of some time later suggested that the circadian rhythms had to do with it).
Question of light. “The colors are not just a physical property”, explains Andreas Bartels, author of the research: “The perception of colors always includes a calculation of the brain on lighting”.
What Bartels says is easily understandable through an example: observing a white sheet illuminated by the sunset light, it will seem reddish us; Observing it on a rainy day, it will seem gray-blue. Yet our mind knows that the sheet is white.
