Scientific paper

Results of the BV photometry of the central parts of 28 normal galaxies. Nucleus and bulge colors are compared for 12 disk galaxies. Galaxies with 'red' nuclei have a nucleus B-V color index which, on the average, is 0.18 + or - 0.3 m greater than the B-V color index of bulges, which may be evidence of a difference in stellar population metallicity by almost an order of magnitude.
