Relation between galaxy colour and stellar mass for the VIPERS PDR-1 sample, within three broader redshift bins. This plot confirms that the most luminous blue galaxies observed in the CMR are in fact very massive objects. In particular, we note how a) the highest-mass edge of the blue cloud evolves with cosmic time, with a few objects as massive as log (M_⋆/M_⊙) ~ 11.5 displaying colours typical of star-forming galaxies; b) conversely, the corresponding highest-mass edge of the RS is substantially frozen over the explored redshift range.
