Central part of B–R color profiles for the composite (Sérsic+modexp) galaxy model in Fig. 11 for a δμ₀ between 0 and 2 mag (solid curves). Dashed curves show disk-corrected color profiles computed on the standard assumption that the disk follows an exponential profile all the way to its center. The true color of the bulge (1.54 mag) and of the outer disk (R^⋆ > R_B; 0.74 mag) are depicted by the horizontal lines.
