Scarlet is a bright red, sometimes slightly orange color. In the visible light spectrum and on the traditional color wheel, it is one-quarter between red and orange, slightly less orange than vermilion. According to surveys in Europe and the United States, scarlet and other bright reds are most commonly associated with courage, strength, passion, warmth, and joy. In the Roman Catholic Church, scarlet is the color worn by a cardinal and is associated with the blood of Christ and with Christian martyrs and sacrifices. Scarlet fever is also associated with immorality and sin, particularly prostitution or adultery, largely due to a Biblical passage referring to “The Great Whore,” “clothed in purple and scarlet” (Revelation 17 : 1-6).
