Quick Summary

Amaranth refers to a genus of coarse annual herbs, known for their clusters of small flowers in various colors, including red and purplish hues. The term also denotes a flower that never fades and a specific color: a pinkish or rosy red. "Amaranth purple" is a deep purplish-red color.12

Historically, amaranth has been used as a red azo dye. However, the azo dye amaranth was banned in the United States in 1976 due to potential health concerns, though it remains approved in other countries. The word "amaranthine" relates to this color or signifies something undying.134
