TL;DR: The color-redshift relation exhibits considerable structure, which may be of use in determining photometric redshifts for quasars from their colors alone as mentioned in this paper, and there is a continuum of properties between Quasar and Seyfert galaxies, and the traditional dividing line (MB = -23) between the two classes of active galactic nuclei.
