Explain the difference between natural and synthetic dyes, including their sources, properties, and applications.

Natural dyes are derived from plants, animals, or minerals and have been used for centuries to color textiles, food, and other materials. Examples include indigo (from plants), cochineal (from insects), and ochre (from minerals). Synthetic dyes, on the other hand, are chemically synthesized compounds developed in laboratories. They offer a wider range of colors, greater stability, and consistency compared to natural dyes and are commonly used in industries such as textiles, cosmetics, and food processing.
