I will discuss how the luminosity distribution of galaxies along the colour-magnitude relation has evolved since z ∼ 0.8. Results are based on observations carried out withing the ESO Distant Cluster Survey (EDisCS), complemented with clusters in the local Universe. I will also present new spectroscopic observations of one cluster from the EDisCS sample, and discuss how these results exclude that post-starburst galaxies represent the dominant channel to move blue star-forming galaxies to the red-sequence.
