The light blue represents water (specifically rain, 'pula', which is vital for the arid country). Black and white represent racial harmony and the national animal, the zebra.
History
Adopted on September 30, 1966, the day of independence. Botswana uniquely chose its own design rather than using Pan-African colors to emphasize its commitment to racial equality and neutral identity.
Construction
A 2:3 ratio. A light blue field with a black horizontal band in the center, bordered by two narrow white stripes.
Color Meanings
blue: Water, rain (Pula), and the sky
