We naturally associate certain colors with different sensations and behaviors: red is linked to danger signals, green conveys tranquility, blue is chosen for relaxation environments, and yellow serves to grab attention. We also know that brands carefully select the shades of their logos and that there is a belief that certain colors can improve concentration.
The central question of the article is whether there really is a neuroscience behind the effects of colors on the brain. The answer, according to the text, is yes, and the phenomenon is more interesting than one might think.
A fundamental point highlighted is that, although it may seem strange, colors do not actually exist in light. What light contains are different wavelengths, which are part of the so-called electromagnetic spectrum.
It is our own nervous system that, when processing the visible spectrum range and comparing the signals reaching the retina, constructs the experience of color.
