The relevance of considering the air-paint interface in the color matching process of a sample and the importance of having a better characterization of the paintings that make up the datábase that is used to reproduce the color of the sample is analyzed. The procedure for color matching paints, whose formulation is unknown, is based on the Kubelka-Munk theory, which assumes that the incident médium is the same as the polymer of the paint. The analysis was performed by matching the sample's color by mixing colored paints with a single pigment to a white paint, mixing paint and colored with a single pigment to a white paint made with pigments Ti02, for which the valúes of K and S are known. Calculations were performed using the software Mathemática 5.0. In was found that the color coordinates are sensitive to the air-paint interface and possibly a more detailed understanding of the formulation of paints to obtain better results in the color matching.
