Evolution of the RS for different selection criteria of early-type galaxies. The colour evolution of the red-sequence as described by the CMR intercepts in (U − V) at M_V − 5 log  h = −20 as a function of redshift. The evolution of the RS is shown for different selection criteria colour-bimodality (blue filled triangles), SED type classification (red open squares) and the classical method (black filled circles). Measurement error bars are displayed for each criteria. All relations are least-square fits to the respective VIPERS selection criteria including the local SDSS reference (filled black square).
