In a preceding paper, Paper I, we provided a simple analytic description of the time dependent luminosity, $L$, and color temperature, $T_{\\rm col}$, valid up to H recombination ($T\\approx0.7$ eV), for explosions of red supergiants with convective polytropic envelopes without significant circum-stellar medium (CSM). The analytic description was calibrated against \"gray\" (frequency-independent) photon diffusion numeric calculations.
