Horizontal bicolour of blue (top) and red (bottom) with a white equilateral triangle on the hoist side containing a golden sun and three stars. Blue for peace; red for courage and patriotism; white for purity. The three stars represent the three main island groups — Luzon, Visayas and Mindanao. The sun's eight rays represent the eight provinces that first revolted against Spain. Unique among national flags — the colours invert in wartime, with red on top to signal a state of war. Adopted on June 12, 1898 by President Emilio Aguinaldo. Practise the Philippines flag in the Flagzio Asia flag quiz across all eight game modes.
