A common characteristic of annatto is that it is derived from a natural plant source. This coloring agent comes from the seeds of the achiote tree, which is native to tropical regions of the Americas. Annatto contains carotenoid pigments, particularly bixin and norbixin, which impart a yellow to orange hue.

This natural origin is significant, especially in the context of cosmetic and food applications, as consumers increasingly seek out products with natural ingredients. Additionally, annatto is valued for its stability and ability to impart color without synthetic additives, making it a popular choice for both cosmetology and culinary uses.

The other options do not accurately reflect the characteristics of annatto. For instance, while annatto can be used in hair dye formulations, it is not exclusively for that purpose and has broader applications. Mentioning that it is used specifically for skin treatments or asserting that it has no effect on color would also misrepresent its properties and benefits as a coloring agent.
