The great mystery of colour finally revealed in a book that involves every field of knowledge, from history to science, from art to psychology. Why does the colour catch our attention and fascinate us until seducing us? The answer is easy: because it is mysterious. Speaking of colour means taking note of its enigmatic nature, of the inexplicable process of sublimation that through the centuries has made it ritual, memory, symbol, emotion. From a physiological and psychological point of view, our reactions to chromatic stimuli are complex. And if in recent decades colours seemed to have disappeared from our homes, today the interior is pervaded by bright and expressive colours, a powerful use of colour on surfaces, accessories and accessories. Because colours arouse emotions, unconscious reactions, assume personal and collective meanings, and a colourful environment can positively or negatively affect our psychophysical well-being. Colour is an extraordinary strategy of nature, a formidable means of information related to the survival of living beings. In the history of humanity, it has been the subject of studies and fascinations, which have given birth to a world of myths, mysteries and curiosities. Yet colour is also linked to a technological and scientific universe of great value linked closely to the universe of living. It is no coincidence that the explosion of new opportunities and decorative technologies or new applications has taken over a dizzying rise of colour, driven by the desire to change, the need to create an ideal environment. This book tries to tell both the colour as history and mystery, both as a technical application, revealing origins and secrets, providing some tools, a few easy rules, practical tips and creative ideas. In order to put the magic of colour into practice in a project or just to treasure it and finally understand why in some environments we are just fine and in others we feel uncomfortable.
