Colorant

A substance that imparts color to another material or substance. Colorants are used to dye, stain, or otherwise add color to various materials, including food, textiles, plastics, cosmetics, and paints. They can be natural (derived from plants, animals, or minerals) or synthetic (chemically manufactured). Colorants function by selectively absorbing and reflecting light within the visible spectrum, creating the perception of color. Factors such as the type of colorant, the material it's applied to, and the application method influence the final color and its durability.
