Color−stellar mass diagrams comparing the breakBRD sample to the low- and high-sSFR parent sample (colors and symbols as in Figure 1). The top and bottom panels are the g − r and u − r colors, respectively. The black dashed lines denote the “green valley” transitional region (Mendel et al. 2013; Schawinski et al. 2014). Although our galaxies are chosen to have red disks (g − r > 0.655), the total galaxy colors are bluer, indicating star formation in the central regions. In both panels, our sample tends to have transitional or blue colors.
