Ratio of the projected two-point correlation function for red and blue galaxies. The data points have been arranged from Fig. 4. The green points refer to data from Li et al. (2006, SDSS at z ∼ 0.1); the diamonds and squares to data from Coil et al. (2017, PRIMUS+DEEP sample at z ∼ 0.5 and z ∼ 0.9). GAEA predictions refer to the realizations run on the MS (black dashed line) and on the PMS (red solid line), as in Fig. 2.
