The flag of Saint Lucia consists of a blue background with a triangle in the center formed by two diagonal white lines. Inside the triangle is a yellow isosceles triangle with a black and white equilateral triangle at its center. The design represents the island's symbolic unity, strength, and hope for the future. Blue symbolizes the island's Caribbean Sea and sky. Yellow represents the sun and prosperity. Black and white triangles reflect the country's unity and the balance of strength and harmony between the people of Saint Lucia. The flag was officially adopted in 1967 after Saint Lucia became a self-governing state. Its unique design and symbolism are intended to reflect the nation's natural beauty and aspiration for progress.
