The positions of N galaxies in the (U-B, B-V) diagram are used together with the colors of various types of galaxies at corresponding redshifts to investigate whether the underlying galaxy components are spirals or ellipticals. It is assumed that an N galaxy consists of a reduced-luminosity quasar and a relatively normal galaxy of unknown morphological type with the quasar in its nucleus. The observed colors of 17 N galaxies are compared with predictions based on different morphological types for the underlying galaxy components. The results obtained are ambiguous in that they yield colors suggesting underlying spiral components for five of the N objects, either spiral or elliptical components for four others, elliptical components for five of them, and no fits for the remaining three. It is concluded that these results are consistent with the diverse galaxy types derived from a few detailed studies and also support the general pattern of continuity among quasars, N galaxies, and classical Seyfert galaxies.
