Currently, there is an immense amount of tools for digital imaging. Such tools, whether they be famous or humble, have a myriad of amazing improvement techniques capable of removing the most destructive degradation or expand the most unnoticeable features. However, almost all of these tools sins in one criterion: they do not have a module for automatic matching of colors to allow for a second instance, a certain interaction with the end user. This type of gap occurs due to the complexity of building models that are able to express the harmony between colors as a closed mathematical relationship or even approximate. In the seminar entitled "Color Harmonization: Automatic Method of Search and Application of Harmonics Schema in Pictures", we present a technique developed by Cohen-Or et al. for matching colors in digital images, which has as base the templates or harmonic schemes developed in the works of Masataka Tokumaru (Color Design Support System Considering Color Harmony - 2002) and Yutaka Matsuda (Matsuda's Color Coordination - 1995).
