Colour magnitude relation for a subsample of 915 galaxies. The rest frame magnitudes were calculated using K-corrections calculator (Chilingarian & Zolotukhin 2012). The distances used for calculating the r-band absolute magnitude (M_r) are based on distances from the literature. The colour coding is based on the sSFR of each galaxy. The dashed line indicates the empirical separation between galaxies with recent episodes of star formation (below the line) and quenched galaxies (above the line). See text for more details.
