Portugal Flag

Portugal Flag: two vertical bands of green (hoist side, two-fifths) and red (three-fifths) with the national coat of arms (armillary sphere and Portuguese shield) centered on the dividing line; explanations for the color meanings are ambiguous, but a popular interpretation has green symbolizing hope and red the blood of those defending the nation.
