The color orange is named after the Dutch Royal Family's surname, the House of Orange-Nassau. William of Orange, their progenitor, was the founding father of the Netherlands. Orange represents national togetherness, and the Dutch wear it to show their national pride. In 1621, an English fleet under the command of James Ier of England defeated a Spanish fleet led by Francisco de Vigo y Solana at the Battle of the Downs. As part of the terms of the surrender, the Spanish king agreed to provide England with 1,000 tons of sweet oranges as a gift. This event sparked a rush to export citrus products to Europe that lasted for more than two centuries. In 17th century Europe, oranges were popular because they were believed to have healing properties. They were used to treat illnesses such as tuberculosis, the flu, and cancer. In North America, the term "orange" originally referred to the fruit itself. When referring to the skin color, it comes from the Latin aurora meaning gold. In Britain, the word "orange" is also used to describe the color between white and black. This originates from the colors of the stocks used by butchers to display meat cuts. These are usually made of wood and painted black or orange so that they stand out against other colors like green or red.
