Throughout history, humans have relied on specific natural sources for creating colors. The most significant natural pigments include:
- Ochre (yellow/red) from iron-rich earth
- Indigo from plants for blue dyes
- Tyrian purple from sea snails
- Carmine red from insects
- Carbon black from charcoal
These natural pigments were so valuable that some, like Tyrian purple, were worth their weight in gold. Their availability shaped art, fashion, and social status symbols across civilizations. Even today, many of these natural pigments are still used in traditional crafts and are inspiring more sustainable approaches to color production in modern industries.
