Rest-frame M_NUV − M_r color magnitude (left) and color stellar mass (right) diagrams of the full SPIRE sample (filled red circles and dashed red histograms) and galaxies undetected in SPIRE (small black points and open black histograms). Galaxies are binned into four different redshift bins and histograms of each sample are normalized (such that the maximal value is unity) for each redshift bin. Only those galaxies detected at high significance in CFHT-WIRDS K_s-band imaging are shown in both panels. In each panel the sample is restricted to those galaxies with stellar masses above the stellar mass limit for each redshift range (given in each panel). The arrow denotes the change in color and (where appropriate) absolute magnitude for an extinction value of E_s(B − V) ~ 0.3 using a Calzetti et al. (2000) extinction law. The arrow is vertical in the right panel because the measured extinction values are already incorporated into the SED-fitting process. The SPIRE-detected sample spans the full range of absolute magnitudes, stellar masses, and, surprisingly, colors in each redshift bin.
