Method for determining the color of an object (10) such as a tooth, by measuring its diffuse spectral reflectance by means of a spectrometer (20), detectors (22) and electronic processing circuits (24, 26,28) associated with a microprocessor (32), consisting in determining the total chromatic difference between the color of the tooth and that of a color chart in a uniform space L * , a * , b * , and the mean square deviation between the diffuse spectral reflectance of the tooth and that of the colors of a color chart, to determine the color of the prosthesis. |
