Fraction of galaxies as a function of the B/T within the MS (black circles), in the upper envelope of the MS (blue stars), in the green valley, and in the passive region (red triangles). The fraction is estimated as the mean in several bin of stellar mass from 1010 to 1011M. The error bars show the dispersion around the mean. The MS upper envelope and the lower envelope (green valley) share the same distribution of galaxies as a function of the B/T: ~40% of the population has B/T > 0.4 vs. 15% of the galaxies in the MS.
