The national flag of Belgium contains three equal vertical bands of black, yellow, and red. The colours were taken from the colours of the Duchy of Brabant, and the vertical design may be based on the flag of France. (source)
Black, gold and red are symbolic of the country's coat of arms; black representing the shield; gold representing the lion, and red representing the lion's claws and tongue. (source)
