The two-color photometry of the Cd galaxy NGC 6166, made at the CFH with the CEA/INAG CCD camera, is presented. For the main galaxy are derived the luminosity profiles, the characteristics of the isophotes as a function of the radius and color gradients. NGC 6166 behaves like a normal elliptical galaxy and does not exhibit any sign of cannibalism or merging. The same studies were applied to the bright spots usually referred to as the nuclei B and C. Calculation of dynamical parameters permits the reconstruction of the three-dimensional shape of the system, which suggests that B and C are cluster galaxies seen in projection rather than additional nuclei.
