Galaxy (left panels), disc (central panels), and bulge (right panels) colours in the Log SFR – Log M_⋆ plane. In the upper panels, the distribution of galaxies in the Log SFR – Log M_⋆ plane is colour-coded according to the weighted average (g−r) colour in each bin. The bins are 0.2 M_⊙ in Log M_⋆ and 0.2 M_⊙ yr^-1 in Log SFR. In the bottom panels, the (g−r) colour is shown as a function of the distance from the MS, Δ_MS, in different bins of stellar mass, represented by different colours (same as Fig. 5). The error bars in the lower panels are obtained via a bootstrapping.
