The contentious title of this discourse was chosen to draw attention to some ideas expressed in a recent publication by Tully, Mould, and Aaronson (1982, hereafter TMA). Two important correlations were discussed in that article. One of those was a correlation between the colors and the intrinsic luminosities or magnitudes of spiral galaxies. The other was a relationship between the color and total mass of disk systems. It is now reasonably accepted that there is also a tight connection between luminosity and total mass.
