Objective: Evaluate the color stability of three flow composite resins, by a digital colorimeter after contact for 30 days with soft drinks. Materials and methods: 21 discs of 8 mm diameter and 2 mm thickness were constructed with flow Alpha, Brilliant, Wave and Opallis resin, the color evaluation was performed by digital colorimeter and the weight with precision balance, after contact in distilled water for 24 hours. The discs were subdivided into four subgroups (n = 7) and submerged for 30 days in 10 ml of Coca-Cola, Fanta or artificial saliva, after a new evaluation of color and weight was performed. The data was analyzed by the Kruskal Wallis, Wilcoxon, Anova and Tukey statistical tests. Results: Alpha Flow resin showed greater resistance to color variation after 30 days in contact with the gaseous beverages evaluated, Coca-Cola showed greater color modification in materials, without significant difference between initial weight and the final weight between the materials. Conclusions: Alpha Flow resin showed greater stability to the color change, Coca-Cola was the gaseous drink with greater influence in the color change; No changes in weight.
