[4] 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.

[5] 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.

[5] The word comes from the Middle English "scarlat", from the Old French escarlate, from the Latin "scarlatum", from the Persian سقرلات saqerlât.

Scarlet dyes were first mentioned in 8th century BC, under the name Armenian Red, and they were described in Persian and Assyrian writings.

Roman officers wore scarlet cloaks called paludamenta,[8] and persons of high rank were referred to as the coccinati, the people of red.

The finest scarlets in ancient times were made from the tiny scale insect called kermes, which fed on certain oak trees in Turkey, Persia, Armenia and other parts of the Middle East.

The insects contained a very strong natural dye, also called kermes, which produced the scarlet color.

"[11] The early Christian church adopted many of the symbols of the Roman Empire, including the importance of the color scarlet.

After the fall of Constantinople to the Turks in 1453, however, the imperial purple was no longer available, and Cardinals began instead to wear scarlet made from kermes.

[14] In the Assumption, by Titian (1516–1518), the figures of God, the Virgin Mary and two apostles are highlighted by their scarlet costumes, painted with vermilion pigment from Venice.

Red flags had first been used as revolutionary emblems, symbolizing the blood of martyrs, during the French Revolution and Paris uprisings in 1848.

Scarlet is the color worn in traditional academic dress in the United Kingdom for those awarded doctorates.

Scarlet red, with or without the use of gold stripes, is the proper color in the Catholic church's liturgy for Palm Sunday, for Good Friday, for Pentecost, for memorials and feasts of saints who were martyred, and for funerals of the Pope or for cardinals.

In the Lutheran tradition, scarlet is the color for paraments for Palm or Passion Sunday, and for all of Holy Week through Maundy Thursday.

This is a variation on the standard RGB or Hex combination that produces a truer Scarlet color on some monitors.
