RGB SDSS images and (g−i) extracted color profiles of six galaxies belonging to the local supercluster sample: a) VCC 1154 is an S0 galaxy with a circumnuclear dusty disk of ~800 pc as shown by an archival HST image. The presence of these structures is easily spotted by a clear deviation towards the red on circumnuclear scale in the (g−i) profile at 3′′ as indicated by the vertical white line. b) The barred spiral galaxy VCC 508. Its circumnuclear star-forming disk (highlighted in the inset) produces a deviation towards blue in the color profile at ~10′′ as indicated by the vertical white line. c) VCC-1690 (Boselli et al. 2016), spiral galaxy with a strong blue AGN nuclear (g−i) color. Its nuclear spectra (shown in the inset) exhibit the key signatures of Post StarBurst (PSB) galaxies. d) Late-type galaxy VCC-873. The AGN activity is strongly obscured by dust and its color profile reaches extreme values. e) Irregular galaxy VCC 664 and its blue, nearly flat color profile. f) The low mass galaxy together with its PSB-like nuclear spectrum. Its central emission strongly deviates towards bluer colors with respect of the outermost region of the galaxy.
