In the 8th century BC, scarlet was used as a dye in places like Persia and Rome. High-ranking Roman officers wore scarlet cloaks to symbolize their power, a practice later adopted by the Catholic Church for cardinals' robes.

During the French Revolution, scarlet became linked with social upheaval, as it represented the blood of martyrs. The color gained more significance with the publication of Nathaniel Hawthorne’s “The Scarlet Letter” in 1850, becoming a universal symbol for forbidden passions.
