With the legalization of display of the Philippine flag, the cloth available in most stores was the red and blue of the flag of the United States, so the flag from 1919 onwards adopted the "National Flag blue" color.
Coa legalización da bandeira filipina, as teas dispoñibles en moitas tendas eran as vermellas e azuis da bandeira de Estados Unidos, polo que a partir de 1919 a bandeira adoptou a cor azul mariño.
