Black and gold are the school colors. The golden hawk is the school's mascot. The stylized hawk profile represents the pride of the Hawaiian people of the Nanakuli valley. The Hawaiian hawk, ?io, is the most predatory, indigenous, air-land animal that soars freely in Hawaii. ?lolani was a sacred hawk of Hawaiian mythology and also one of the names of King Kamehameha IV (Alexander Liholiho ?lolani). ?lolani means "Hawk of Heaven" or Royal Hawk" and the flight of the ?io was believed to be a sign of royalty. A Hawaiian proverb from ancient times states: "He ?io au, he manu l ka lewa lani" ("I am an ?io, the bird that soars in the heavenly space"). This is meant to be a boast. The highest chiefs were often called ?io (hawk), "king of the Hawaiian birds." Black and gold were treasured (kapu, taboo) colors as only the rarest birds' feathers were used to adorn royal cloaks, headdress and scepters. The school's motto is "Kulia l Ka Nu'u" (We strive for the Highest).
