Che

This is a rather simple watercolor painting.  I used a stencil that I had used on a previous piece of artwork for a friend.  The image is of the controversial Ernesto "Che" Guevara, who was a major figure of the Cuban Revolution and has become a symbol of the counterculture and rebellion.  The image shown here is actually reversed from the original 1960 photo by Alberto Korda titled, "Guerrillero Heroico" (English:  Heroic Guerrilla Fighter)  It may be the the world's most famous photograph and the Victoria & Albert Museum says that the photograph has been reproduced more than any other image in photography.  Can you tell what the colors and the blue stripes represent?
