The national flag of the Philippines (Filipino: Pambansang Watawat ng Pilipinas) is a horizontal bicolor flag with equal bands of royal blue and crimson red, with a white, equilateral chevron at the hoist. In the center of the triangle is a golden-yellow sun with eight primary rays, to represent the original eight provinces that rebelled against the Spanish during the 1896 Philippine Revolution. At each vertex of the triangle is a five-pointed, golden-yellow star, each of which representing one of the country's three main island groups—Luzon, Visayas (though originally referring to the island of Panay), and Mindanao. The white triangle at the hoist represents liberty, equality, and fraternity. A unique feature of this flag is its usage to indicate a state of war if it is displayed with the red side on top, which is effectively achieved by flipping the flag upside-down.
