Mass-to-light ratio as a function of u − r (left column) and g − r (right column) color for the SDSS-matched sample of the modeled galaxies. In the bottom row, the u − r and g − r colors are corrected for extinction while in the top row, they are not. The galaxies are color-coded based on their E(B − V). The dashed magenta line represents the extinction-independent relation of Eq. (6), and the dashed-dotted lines the extinction-dependent, drawn for some discrete E(B − V) values as shown in the legend using the parameters presented in Table 3. The dotted black line shows the relations of Wen et al. (2013).
