The Baguio Centennial logo is visually divided into four main parts making up the wings of the butterfly. Each distinct part is given a specific color that suggests the four elements of earth (green), fire (red), air (yellow), and water (blue). Within each wing are stylized forms that portray the city’s physical, cultural, and social aspects:
Blue Wing: dancing figures symbolize the people of Baguio, its cosmopolitan population, and vibrant city life. It depicts a place where different cultures converge and live in harmony.
Green Wing: portrays the physical icons of Baguio, the pine forests, and landmarks that have made the city famous for the past one hundred years; the Cordillera hut-inspired Convention Center, the City Hall, the Our Lady of Atonement Cathedral, and the historical Camp John Hay Bell Ampitheater.
Yellow Wing:dominated by a sunflower that symbolizes the spirit of Panagbenga: the celebration of life, the blossoming of our native culture, the promotion of art, and a united community.
Red Wing: a stylized strawberry, one of the city’s most popular market produce, symbolizing Baguio’s history as a center of commerce in the Northern Philippines. While the strawberry may not be a “native” Baguio product, it is placed here to pay homage to our municipal neighbors. Baguio could never have been, and would never be, if not for our neighboring towns.
The butterfly logo is skewed at an angle to provide a visual sense of movement, flight… and an upward trajectory depicts the future-forward thinking of the City.
It is hoped that this logo becomes a catalyst for change so, when September 1, 2009 inevitably arrives, we can honestly tell the world that Baguio is a city that cares.
