The flag of Algeria is represented by two equal vertical bands of green (hoist side) and white; a red, five-pointed star within a red crescent centered over the two-color boundary; the colors represent Islam (green), purity and peace (white), and liberty (red); the crescent and star are also Islamic symbols, but the crescent is more closed than those of other Muslim countries because the Algerians believe the long crescent horns bring happiness.
