This study evaluated the validity of the color selection results obtained from digital cameras. Four observers matched the colors of 30 extracted maxillary incisors under daylight conditions. Two different digital cameras, with 1.5- and 5.0-megapixel resolutions, were used to select the color of the standardized circular area with 3 reference points on the same teeth; a spectrophotometer was also used, and the results were compared with the human and camera observations. The highest significant agreement (60% agreement with the spectrophotometric values) was found with the 5.0-megapixel camera. It appears that the resolution capacity of a digital camera can increase the reliability of color selection.
