ABSTRACT OF THE DISCLOSURE The present invention provides a process for coloring, by electroplating, an aluminium or aluminium alloy article previously subjected to anodic oxidation, in which co-deposition of at least one metal selected from the group consisting of nickel, cobalt, and cadmium with at least one auxiliary metal is carried out by stirring, applying an alternating voltage between said article and a counterelectrode immersed in a bath containing the salts of the metals; in the process the alternating voltage, for each period, has a zero value for at least a certain period of time, and the bath has a pH below or equal to 1.8 and contains at least a salt of the auxiliary metal selected from the group consisting of the copper and tin salts, the concentration of the auxiliary metal salt in the bath being lower than 2.5 g/l and the concentration in the bath of the salt selected from the Ni, Co and Cd salt being less than 200 g/l.
