Scarletis a bright red color, sometimes with a slightly orange tinge. In the spectrum of visible light, and on the traditional color wheel, it is one-quarter of the way between red and orange, slightly less orange than vermilion.
According to surveys in Europe and the United States, scarlet and other bright shades of red are the colors most associated with courage, force, passion, heat, and joy. In the Roman Catholic Church,scarlet is the color worn by a cardinal, and is associated with the blood of Christ and the Christian martyrs, and with sacrifice.
Scarlet is also associated with immorality and sin, particularly prostitution or adultery, largely because of a passage referring to "The Great Harlot", "dressed in purple and scarlet",in the Bible (Revelation 17:1–6).
