Communist symbolism usually incorporates symbols representing the industrial workers and/or the peasants of a country.
Usually these symbols, along with a pentangle representing the five inhabited continents, appear in yellow on a red background representing revolution. The Flag of the Soviet Union incorporated a yellow-outlined red star and a yellow hammer and sickle on red. The flags of Vietnam, China, Angola, and Congo-Brazzaville would all incorporate similar symbolism under communist rule. The hammer and sickle have become the pan-communist symbol, appearing on the flags of most communist parties around the world.
