Indigo

From WikiMD's Wellness Encyclopedia

Indigo is a deep and rich color close to the color wheel blue (a primary color in the RGB color space), as well as to some variants of ultramarine, based on the ancient dye of the same name. The word "indigo" comes from the Latin for "Indian", as the dye was originally imported to Europe from India.

History[edit | edit source]

The use of indigo dye dates back thousands of years, with its origins traced to India. It was a major export product in the 15th century, and was used in many types of industries, such as textiles, printing, and painting.

Production[edit | edit source]

Indigo dye is produced from the plant Indigofera tinctoria, but most dye is produced synthetically today. The production process involves fermenting the leaves of the plant, which produces a blue dye.

Uses[edit | edit source]

Indigo is used in many industries, including textiles, where it is the dye used to produce the traditional blue color in denim jeans. It is also used in printing, painting, and other types of manufacturing.

Health effects[edit | edit source]

While indigo is generally considered safe, there have been some concerns about potential health effects. Some studies have suggested that exposure to indigo dye can cause skin irritation and other allergic reactions.
