The primary color in the flag of France is blue. The French flag, known as the Tricolore, consists of three vertical stripes: blue on the left, white in the middle, and red on the right. Blue is often associated with liberty and represents the ideals of the French Revolution. The design has become emblematic of French national identity and values. While blue is the primary color, the interplay with white and red also symbolizes the country's heritage and history, alongside its principles of freedom, equality, and fraternity.
