A molded article includes a polycarbonate resin and a colorant, and the molded article, when tested using a 3 mm color plaque, includes a color difference delta E (dE*) of less than about 0.6 following molding under abusive molding conditions as compared to a reference article molded under standard processing conditions. The molded article may include a color difference delta b (db*) of less thanabout 0.3 after being molded under the abusive molding conditions. The molded article may also exhibit a shift in wavelength of maximum absorbance of less than about 5 nm after being molded under theabusive molding conditions and/or a difference in absorbance intensity of less than about 15% after being molded under the abusive molding conditions as compared to a reference article molded under standard processing conditions. Methods for forming a molded article in accordance with the above are also described.
