A color additive is a substance that is added to products to enhance their color. These additives can be natural, like those derived from plants, or synthetic, created through chemical processes. They are commonly used in food, cosmetics, and pharmaceuticals to make items more visually appealing and to indicate flavor or quality. In the United States, the use of color additives is regulated by the Food and Drug Administration (FDA). Before a color additive can be used, it must be tested for safety and approved by the FDA. This ensures that the additives are safe for consumption and do not pose health risks to consumers.
