UB color–mass diagram of the mass-selected samples of CL1252 early- (filled red circles) and late-type (red stars) galaxies as well as of CDFS field early- (filled blue circles) and late-type (blue stars) galaxies. Uncertainties in the stellar mass are ~0.15 dex. Field ETG galaxies are distributed around the cluster red-sequence, although with a larger scatter.
