In addition to the constitution, the delegates selected Athens as the new national capital, though it had yet to be conquered from the Ottoman Empire. They also selected a new standard for the troops, a "white cross on an azure field", a new naval flag, and new national colours, sky blue and white; the new colours replaced those used by Alexander Ypsilantis, and the black used by the Filiki Eteria, and were specified in the Constitution. The flag was raised at the Acrocorinth after its capture on 26 June 1822.
In the Greco-Italian War, during which Italian forces occupied parts of Greece in 1940 and 1941, Greek civilians in Póthia would taunt the occupying forces by painting their houses in blue and white. Some houses still retain this colouration among the more typical pink and ochre buildings.
The coat of arms of Greece consists of a white cross on a blue escutcheon which is surrounded by two laurel branches. Although the tincture for the branches is designated as "proper", which implies the colour found in nature, it is usually displayed with blue laurel branches; the president, military, and security services use golden branches instead. The Flag of Greece is also blue and white, as defined by Law 851/1978 Regarding the National Flag. It specifies the colour of "cyan" (Greek: κυανό, kyano), meaning "blue", so the shade of blue is ambiguous.
^Lampros & Polites 1896, p. 234"When the herald called out the name of Louis, and when the victor in the Marathon Race ascended the platform, the Stadion resounded with cheers which seemed to take no end. Pigeons adorned, with ribbons of the national colours of Greece, were let flying across the Stadion; national flags and handkerchiefs were agitated in the air; nobody can even attempt to describe the joy, the enthusiasm of the Greek people; the foreign guests were not a little astonished by it."
