Many living things use orange in a very special way. Carrots, pumpkins, and sweet potatoes all have this bright hue. This color comes from carotenes, which are a type of photosynthetic pigment. These pigments help plants by turning light from the sun into stored energy. This energy helps the plants grow big and strong. You can also see orange in autumn leaves. This happens after the green chlorophyll is removed from the leaves.

Humans have used orange for a very long time. Artists in ancient Egypt used a mineral called realgar for tomb paintings. In ancient India, people used orange carnelians during the Indus Valley Civilisation. Some people even used a mineral called orpiment to make orange colors. Orpiment was a major item of trade in the Roman Empire. It was used as medicine in ancient China, even though it is highly toxic. Alchemists in China and the West also liked it because of its yellow-orange color.

The name of the color actually comes from the fruit. Before the word "orange" was used in English, people called the color yellow-red. In the 1500s, Portuguese merchants brought orange trees to Europe from Asia. They also brought the word for the fruit with them. This word eventually became the name for the color we use today. In the 17th century, the name shifted from describing the fruit to describing the color itself.

Orange is also a very important color in history and politics. The House of Orange-Nassau is a famous royal family from Europe. They are the national family of the Netherlands. This family even helped the Netherlands win its independence from Spain. In the United States, the flag of New York City has an orange stripe to remember Dutch colonists.

Orange is a vibrant color located between yellow and red on the spectrum of visible light. Human eyes perceive this hue when observing light with a dominant wavelength between roughly 585 and 620 nanometres.

In traditional color theory, orange is a secondary color of pigments created by mixing yellow and red. In the RGB color model, it is classified as a tertiary color. This color is not just a visual phenomenon; it is deeply connected to biology, history, and human culture.

In the natural world, orange often signals biological processes. Many fruits and vegetables, such as carrots, pumpkins, and sweet potatoes, owe their color to carotenes. Carotenes are a type of photosynthetic pigment. These pigments allow plants to absorb light energy from the Sun and convert it into chemical energy for growth. You can also see this color in autumn leaves. As the green chlorophyll is removed from the leaves, the orange pigments become visible. This process reveals colors that were hidden during the growing season.

Humans have used orange pigments for thousands of years. In ancient Egypt, artists used a mineral called realgar for tomb paintings. During the Indus Valley Civilisation, people used orange carnelians. Another important mineral was orpiment, which has a yellow-orange color. Orpiment was a major trade item in the Roman Empire. In ancient China, it was even used as medicine, though it is highly toxic because it contains arsenic. Alchemists in both China and the West also favored orpiment as they searched for ways to make gold.

The name of the color actually comes from the fruit. Before the word "orange" entered the English language, people used different names. They often called the color "yellow-red" or used the word "saffron." Some even used "red" to describe orange things, like red deer or the Red Planet. The English word comes from the fruit, which has roots in Arabic, Persian, and Sanskrit. Portuguese merchants brought orange trees to Europe from Asia in the late 15th and early 16th centuries. They also brought the name of the fruit, which eventually became the name for the color itself.

History is also shaped by the House of Orange-Nassau. This influential European royal house originated in the Principality of Orange. The principality was named after a Roman-Celtic settlement dedicated to the water god Arausio, not the fruit. The family adopted the name and the color in the 1570s. Because they supported Protestantism, the color became associated with that faith. William III of Orange became King of England in 1689. This made orange an important political color in Britain and Europe.

In the 18th and 19th centuries, new technology changed how artists used orange. In 1797, Louis Vauquelin discovered the mineral crocoite, which led to the invention of synthetic chrome orange in 1809. Later, artists could use cobalt orange, made from cadmium sulphide and cadmium selenide. The invention of the metal paint tube in 1841 allowed painters to work outdoors. This helped Impressionist painters like Claude Monet use orange to capture natural light. Vincent van Gogh was perhaps the most famous user of the color. He used orange and yellow to represent the sunlight of Provence, often placing them against blue skies to create intense contrast.

Today, orange serves many practical and symbolic purposes. Because it is highly visible, it is used for safety. US Navy pilots used orange inflatable life jackets in the Pacific during World War II so search planes could find them. Cyclists and highway workers also wear orange to avoid accidents. However, the color has also been linked to difficult history. The herbicide Agent Orange was used during the Vietnam War to remove forest cover. Though the name came from the color of its steel storage drums, the chemical was toxic.

In politics, orange remains significant. It is the color of Christian democracy in many countries. It was also the symbol of the Orange Revolution in Ukraine in 2004.
