Blue and red were the colours of the town of Paris. (the colours were meant to honour the two patrons saints of the town Saint-Denis and Saint-Martin. The emblem of the town is still blue and red today. White was the colour of the monarchy, especially for the last kings before the revolution. At the beginning of the revolution, the king Louis XVI visited the city hal and in a gesture towards the populace, he took the blue and red cocard and put it on his hat next to the white one. The associated colours were chosen by the revolutionaries to create the French flag, offcially adopted in 1974.
