President Macron of France changed the blue color of the French flag. He made the blue darker again, after it was set to be the same blue as that of the European Union flag back in the 1970s. (Then president Giscard d’Estaing thought the different shades of blue clashed during photo ops).

I agree with Macron, the darker blue looks better, flags have a history, and i don’t think the two shades of blue clash at all. When doing design work, pay attention to flags. They have very specific colors (like logos), and very specific aspect ratios.
