Objective: The present study aimed to verify the color correspondence of composite resins in relation to the Vita Scale, through the visual method and the digital method. Material and method: This is an in vitro laboratory study carried out with 24 specimens, using resins composed of 8 different resin brands, in colors A1, A2 and A3, which were subjected to the analysis of color taking, both by the visual method as well as by the digital method with the aid of a scanner. The data were analyzed in a descriptive and analytical way using the Chi-square test and the Fisher test to compare the frequencies of coincidences by the visual and digital method, according to the brand, color and method. Results: 41.67% of the resins showed color matching when evaluated by the visual method, while the digital method showed 29.17% color matching. The proposed colors were identified neither by the digital method nor by the visual method (92.6%), with a significant difference (p <0.05). When compared the frequencies of coincidences, there were more coincidences by identifying the color by the visual method than by the digital method (p <0.05). Conclusion: The digital and classic visual methods showed little correspondence between the color proposed by the manufacturers and the color obtained after polymerization of resins. And when comparing the frequencies of color coincidences, they were more identified by the visual method than by the digital method.
