France changed its flag.. no kidding they really did.

It was revealed that Emmanuel Macron took the decision to change the Flag of France, making the blue a deep blue "Bleu marine". This is not a new design, but the one that was used in France until 1976 when Giscard d'Estaing made the blue closer to EU colours.
