Abstract Results are shown for photoelectric B and V observations of Markarian 421 (Mrk 421) from 1982 to 1991. It is found that one can explain the dependence of the color indices (B-V) averaged for a season on the B magnitude within a two-component model (an underlying galaxy + a variable point source). It is determined that the color index (B-V) var of the variable source does not change, and the observed variability of the color index is caused by variation of the contribution from the variable source to the total flux.
