Color variations in V Sge during various states of its activity in the course of 1995-1997 show that B-V gets bluer while U-B does not change significantly. Comparison of our dala with the outburst observed by Herbig shows that although the character of the activity in V Sge changed during the last decades the colors and their variations remained similar.
