Experimental analysis of the obtained samples was performed by scanning electron microscopy with energy dispersive spectrometer (SEM / EDS), on a laboratory instrument brand "JEOL - Tokyo" model "JSM 6460 LV". In order to ensure better electrical conductivity of samples of colored materials, the samples were prepared with an ultrathin layer of gold by a nanotechnological process in a vacuum chamber (which is an integral part of a scanning microscope), and only then recorded and analyzed under different magnifications. Electron microscopy uses beams of very high energy electrons that cause changes in the nuclei of atoms that make up color molecules. The results of the intensity measurement "fell" in the area of wave vectors between (10-7-10-9) cm-1, which corresponds to energies of (2 - 6.5) 10-16 J, and means that the measurement results are the result of characteristic X-rays radiations. Here, the functions Cn (k) are found for all rainbow colors and their maximum abscissas are determined, which are marked with λm. In this case of color analysis at high energies, it was found that there is a law of magnitude λm of the type of paint. Legality can be formulated with the following statement: the largest abscissa of the maximum has a red color and it decreases towards purple, where its value is the smallest.

Ključne reči: Forensic analysis of colors; scanning electron microscopy; distribution superposition.
