Abstract

The observations of selected cataclysmic variables (the dwarf novae V1504 Cyg and GO Com; postnovae Q Cyg, V446 Her and DI Lac) observed at the Crimean astrophysical observatory and Crimean laboratory of the Sternberg astronomical institute in 1995–2007 are presented. Their behavior on the “magnitude (V) – color (V-R)” diagram is given. The behavior of the dwarf novae is similar to these of postnovae. An average they show the break of the “brightness – color” dependence. The V–R grows slowly or does not grow at all before the break than after it.
