Flag of Delaware
Delaware’s flag is colonial blue with a buff diamond holding the state coat of arms, and the date December 7, 1787 beneath it: the day Delaware became the first state to ratify the US Constitution. The State of Delaware says that, according to members of the commission that designed it, the shades of buff and blue are those of General George Washington’s uniform.

How to read it
The flag law, 29 Del. C. § 306, describes a background of colonial blue surrounding a diamond of buff, which holds the coat of arms in the colours set by law, with “December 7, 1787” underneath. The colours are fixed by the Textile Color Card Association: colonial blue is “arno blue”, Cable No. 10663, and buff “golden beige”, Cable No. 10781, as measured by the National Bureau of Standards in a test dated November 18, 1954, on file with the Delaware Public Archives. The section colours the arms too: the husbandman in grey-brown trousers, a red shirt and a brown hat, with a brown hoe; the rifleman in green, with buff binding, bag and leggings; the shield framed in shaded yellow, with an orange top panel, a blue centre and a white lower panel, a red-brown ox, green grass and corn and yellow wheat; a twisted blue and silver wreath; a ship with a dark hull and white sails; and the date in white. A commission authorized in 1913 chose the flag on July 24, 1913. Its design was left out of the Delaware Code, and a law approved on June 13, 1955 wrote it in. The Governor’s flag is the same with a gold fringe, carried on a pole topped with a model of a blue hen’s fighting cock (§ 307).

What the coat of arms shows
The arms come from the Great Seal (§ 301): a shield divided across, gold above with a sheaf of wheat and an ear of corn, silver below with an ox, and a wavy blue band between; a husbandman with a hilling hoe and a rifleman as supporters; and a ship under full sail as the crest. Delaware.gov explains each part. The wheat sheaf, from the Sussex County seal, is Delaware’s farming; the ship, New Castle County’s shipbuilding and the state’s coastal trade; the corn, from the Kent County seal, farming again; the farmer’s hoe, the central role of farming; the militiaman, the citizen-soldier; the ox, animal husbandry; and the water above the ox, the Delaware River.
Telling it from New Jersey’s flag
New Jersey’s flag has the same two colours the other way round: its whole field is buff, with no diamond and no date, and its arms show Liberty and Ceres either side of a shield of three ploughs.

Fleming suggested the red cross, added in 1900, so that the flag would not look like a white flag of truce or surrender when it hung still; the law gives it no other meaning.

Each star stands for a state or the Federal District; the 1889 flag decree said the green and yellow, kept from the empire, recall the victories of the army and navy.
