Inversely to the chromatic variability of the world, extensive researches in the field of colour and linguistics indicate that we commonly use only eleven to fifteen words to define the chromas that we best distinguish, and this number, in more complex languages. However, with each perceived colour, a whole spectrum of words emerges to describe, narrate, express what is, according to Merleau-Ponty “colour, the echo of the body after seeing things” (in L'Oeil et L' Esprit, 1964).
