Natural dyes are created through various chemical processes that extract and bind colored compounds from organic materials. The key components include:
- Chromophores: Chemical structures that absorb specific wavelengths of light
- Mordants: Metallic compounds that help bind dyes to materials
- Tannins: Natural compounds that can both create color and help fix dyes
The extraction process typically involves soaking or boiling plant materials to release water-soluble pigments. The effectiveness of natural dyes depends on factors like pH levels, temperature, and the presence of mordants. For example, madder root produces red dyes through compounds called anthraquinones, while indigo creates blue through a complex oxidation process.
