The Flag of the Netherlands consists of three horizontal stripes: red at the top, white in the middle, and blue at the bottom. This tricolor design has been in use since the 16th century and is one of the oldest national flags in the world. The colors are often associated with the House of Orange, which played a significant role in the country's history. The flag's proportions are 2:3, meaning its width is 1.5 times its height. It is a symbol of Dutch identity and is displayed during national holidays, such as King's Day, and at various public events.
