The photometric behavior of the spotted primary component of the eclipsing dwarf system V772 Her (G0V + M5V) is considered based on long-term multicolor photoelectric observations. The total photometric effect caused by starspots reaches up to 0.m19. Our simulations showed that the area of the spotted regions can reach up to 13% of the total surface of the star. The spots are 1800 K cooler than the unspotted photosphere and are located at low latitudes.
