Fruits and vegetables provide natural food coloring. The red of paprika fruits, the yellow of turmeric roots, the orange-red of annatto seeds, the yellow-orange of marigold blooms, and the green of leaves are natural colors.
A Natural Color that is suited for the purpose can be obtained by considering parameters such as pH, heat, light, storage, and other substances.
For usage in water-based goods and applications, all-natural food colors are available in water-soluble and dispersible forms. They can also be delivered as powder. Spray-dried versions of these natural colors are also available for specialized purposes.
