Colour-dependent projected correlation functions in three redshift intervals from z = 0.2 to z = 2.1, both observed in the VVDS-Deep and predicted by the SAM. In each panel, the filled circles (red galaxies) and filled squares (blue galaxies) correspond to VVDS-Deep measurements, while the dashed curves and associated shaded areas correspond to the mean and the 1σ dispersion among the Omocks. The dotted curves are the mean w_p(r_p) obtained by rescaling the predicted correlations function to σ₈ = 0.81 as described in Sect. 4.2. In all panels, both for VVDS-Deep and SAM galaxies, the w_p(r_p) with higher global amplitude corresponds to that of red galaxies.
