Every element of the Philippine Flag has some sort of symbolism. This design was conceptualized by Emilio Aguinaldo while he was in exile in Hong Kong.
The white triangle stands for equality and fraternity. The blue field for peace, truth and justice. The red field for patriotism and valor.
The white triangle has three stars, symbolizing the three main groups of islands of the Philippines – Luzon, Visayas and Mindanao. At the center of these stars is a sun with eight rays, said to represent the first eight provinces of the Philippines – Batangas, Bulacan, Cavite, Laguna, Manila, Nueva Ecija, Pampanga, and Tarlac.
The Philippine flag is present in almost all buildings all over the country. Just like in other countries, it is honored in ceremonies while the National Anthem is sung. Replicas of the Philippine flag is especially popular during Independence Day on June 12.
In times of mourning, the Philippine flag is raised half-mast. During war, it is hung with the red field on top to signify courage and in more basic terms, bloodshed.
