An apparatus including a measuring head, equipped with light sources for lighting one part of a bodywork of which the color is to be reproduced with a receiver for picking up the light reflected in each of a plurality of preset wavelength in order to produce a signal representing the reflectance of the surface in each wavelength. The apparatus also includes a device for calculating, for each wavelength, the reflectance for any combination of basic shades or bases from among a predetermined set off bases, and apparatus for continuously comparing the measured reflectance with the calculated reflectance in order to find a suitable paint formulation. A starting formulation given by the particular combination of bases corresponding to the color reference of the bodywork to be repaired may be modified, until the difference between the calculated reflectance values and measured reflectance values reaches a minimum or becomes smaller than a preset threshold.
