Properties of the spheroid (red circles) and disc (blue circles) components: g–i (top panel) and sSFR (bottom panel) as a function of M_Star. For comparison, we include the same observations as in Fig. 9 (black asterisks). We depict blue star-forming galactic objects as black open squares, and the limiting lines reported by Lacerna et al. (2014) between red and blue galaxies in the bottom panel, and between star-forming and non-star-forming galaxies in the top panel.
