"Having now sufficiently investigated the exhibition of color in this phenomenon, we repeat that we cannot admit it to be an elementary phenomenon."4

In relation to the object (material) whose color will be evaluated, this could be characterized by its spectral characteristics: transmittance curve for transparent objects, reflectance for opaque objects, but both curves are required for translucent materials. Opaque colored objects always reflect light of their own color and absorb that of the complementary colors.1 During the process of color on matter, it is clear that it is possible to find achromatic colors that are devoid of one, or of proportions
