Abstract
Based on a comparison of similar colour indices we investigate the effects of luminosity and metallicity that influence the Strömgren and Vilnius photometric quantities for different spectral types. We notice significant differences for similar indices, apparently due to small deviations of central wavelengths and band-widths of the filters. For the G-K type stars of moderate luminosity we interpret the difference introduced by v and X pass-bands as an log g effect, reflecting the presence of H&K Ca II stellar lines in these spectral types. We discuss a possible influence of the H&K Ca II lines on the luminosities derived from the Vilnius classification diagrams.
