Total number and fraction of red (filled circles) and blue (filled squares) galaxies as a function of redshift in the VVDS-Deep and in the SAM. The symbols with error bars are the VVDS-Deep measurements while solid curves and associated shaded areas correspond to the predicted mean fractions and 1σ field-to-field dispersions among the Omocks. The dotted curves are the mean predictions of the Cmocks. In both upper and lower panel, higher curves and symbols correspond to blue galaxies.
