Annatto, sometimes called roucou or achiote, is derived from the seeds of the achiote trees of tropical and subtropical regions around the world. The seeds are sourced to produce a carotenoid-based yellow to orange food coloring and flavor.

Annatto is commonly used in Latin American and Caribbean cuisines as both a coloring and flavoring agent. Central and South American natives use the seeds to make body paint and lipstick. For this reason, the achiote is sometimes called the "lipstick-tree". Achiote originated in South America and has spread in popularity to many parts of Asia. It is also grown in other tropical or subtropical regions of the world, including Central America, Africa and Asia. Annatto is a naturally intense dye which can range in color from bright yellow to deep orange. Many commercially made food products utilize annatto for its potent color.
