摘要
The color of an object is defined as the color of the light it reflects. The color is therefore not a characteristic of the object but rather a characteristic of the light that illuminates it, thus objects are quite simply “color thieves”. However, the reflected light is subject to the Snell-Descartes law of reflection: the angle of incidence is equal to the angle of reflection. This law implies that the color of the object can only be seen by observers occupying specific positions. But we all know that this is not the case, the color of the object is seen by any observer regardless of position. In this work, we then introduce a new way to define the color of an object based on spectroscopic principles: The atoms of the object absorb the white light of the sun and subsequently they emit radiation of which frequency corresponds only to the color of the object.
