The way in which we see colors does not depend only on how objects reflect light and on the characteristics of our visual system: the brain processes the chromatic inputs into mental images useful for interpreting the world around us.
We humans have primordial reactions identical to colors that are rooted in our evolutionary history: for example, experience has allowed us to associate visceral emotions with red that evoke pleasure in us but also danger, emergency.
Color has a very strong power on the psyche, it influences our mood: recent studies confirm that just wearing red clothes could benefit us in competitive situations. Blue, on the other hand, is linked to innate ancestral responses and has a calming value, but each of us also has individual responses to color vision: there are those who have developed real phobias related to a specific color, those who have physiological difficulties in distinguish certain colors such as red and green and who even sees the world in black and white. Dr. Beau Lotto has conducted a series of experiments to investigate how each of us perceives color: in this exam we were asked a heterogeneous sample of people to match 49 tiles of different colors following a random pattern; although there are billions of possible combinations, Lotto has verified that people tend to recreate combinations similar to the images they see in everyday life.
Analyzing the collected data it emerges that people of different sex, age and social background perceive color in a different way and it would seem that even the language with which we describe colors influences our way of perceiving them!
The Himba tribe, for example, in northern Namibia, uses only 5 words to represent all the colors: milk is white, but for them the water is also white. Tests carried out by scientist Serge Caparos show that the Himba take longer to identify colors for which they do not have a specific term.Our mind then processes the colors: emotions, memories, experiences and even language help to shape the our chromatic vision.
