Coreopsis is not well recorded but is probably one of the sources of yellow to orange dyes of pre-Columbian civilization from central and South America. The Cherokees and Apaches used Coreopsis as source of red dye.
The flavonoids in Coreopsis are a mixture of chalcones and aurones (also called pigments antochlors) whose structures are known only since the mid-20th century.
