Insect-based dyes are natural colorants derived from specific insects, primarily used in textiles and art. One of the most well-known examples is cochineal, a scale insect that produces a vibrant red dye called carminic acid. This dye has been used for centuries in various cultures and is valued for its rich color and lightfastness. These dyes are considered more sustainable than synthetic alternatives, as they are biodegradable and often produced with less environmental impact. Insect-based dyes can be used on a variety of materials, including cotton, silk, and wool, making them versatile for artists and manufacturers alike.
