The National Flag of the Philippines is a horizontal bicolor with equal bands of blue and red, and with a white equilateral triangle based at the hoist side; in the center of the triangle is a golden yellow sun with eight primary rays, each containing three individual rays; and at each corner of the triangle is a five-pointed golden yellow star.

The flag is displayed with the blue field on top in times of peace, and with the red field on top in times of war.

The flag was first conceptualized by Emilio Aguinaldo. The first flag was sewn in Hong Kong by Marcela de Agoncillo, her daughter Lorenza, and Doña Delfina Herbosa de Natividad, niece of José Rizal, the Philippines' national hero.
