The possibility of using color orientation maps obtained from the surface of polycrystalline specimens to determine the characteristics of the substructure and the orientation inhomogeneity has been studied experimentally. It is shown that a consistent and independent review of the color orientation maps in hues of red, green, blue and gray colors, and use of specially developed technique for the visualization of color hues which are not visually different on the color orientation maps allow not only to receive all the necessary characteristics of the substructure and the orientation inhomogeneity, but to study of their change in situ under plastic deformation of the samples.
