Abstract
We re-investigate the Lira-Phillips relation of Type Ia supernovae and its use for determination of reddening of individual SNe Ia. We use a more recent, more extensive dataset of SNe Ia with negligible reddening, and attempt to refine the prediction of the intrinsic B-V color index. We find that the Lira-Phillips relation is valid, but the dispersion of the intrinsic B-V colors is substantial. The present data may suggest slightly redder intrinsic colors, thus, the previously calculated total extinctions (and the corresponding distance moduli) should be decreased by $\sim 0.19$ mag.
