Schombert, James M. ; Wallin, John F. Abstract Multicolor surface photometry is presented for shell galaxy Arp 227 (NGC 474). The profile shape and colors confirm that this object is an SO. Unlike previous color measurements of blue shells (Carter et al. 1982; Forte et al. 1986), the shells of this system are red (B-V = 0.90 + or - 0.08), identical within the errors to the color of the parent galaxy (B-V = 0.94). Possible origins for the shells are tidally liberated material from the parent galaxy, stripped matter from a nearby companion, or the merger with a low-luminosity elliptical.
