Photometric and colorimetric parameters of several Markarian and normal galaxies were compared. By the mean weighted surface brightnesses the 9 Markarian galaxies are 0.7 mag brighter than 7 normals while the mean surface brightnesses of both samples calculated the usual way are practically the same. For both samples a large dispersion is observed in (U-B, B-V) diagrams constructed for measured points in each galaxy. About 30% of integral intensity of galaxies in both samples is due to the areas located above the black body line in the (U-B, B-V) diagrams. The scatter in colors is much larger for the Markarian galaxies.
