Photoelectric UBV observations were obtained for 92 Markarian galaxies and an additional five Seyfert galaxies to study the colors of the continuous spectra in these objects. A total of 28 Seyfert galaxies, 42 other galaxies with bright blue nuclei, and 27 diffuse galaxies were included. Multiaperture observations are presented for seven of these galaxies. It was found that galaxies spectroscopically classified as Seyfert galaxies because of broad nuclear emission lines have UBV colors corresponding to nonthermal continua, but the numerous Markarian galaxies with bright nuclei having narrow emission lines do not have such colors; instead, the ultraviolet continua of these galaxies apparently arise from hot stars. New spectroscopic and photographic observations are also presented for some Markarian galaxies of particular interest, including Markarian 3 and 205. (auth)
