Revelation 17:4

“And the woman was arrayed in purple and scarlet colour, etc.] Which may be expressive of her grandeur, authority, and power, sitting as a queen, and sovereign in the empire, ruling over kingdoms and nations in it; and also of her bloody disposition to the saints, with whose blood she is afterwards said to be drunk; and decked with gold and precious stones, and pearls; which may denote her hypocrisy, she being gilded with these things, as the word signifies, when she was inwardly rotten, corrupt, and filthy; and may point out the things by which persons have been enticed into the communion of the church of Rome, and to comply with her idolatrous worship and practices; and may also respect the…”

“The color scarlet, it is remarkable, is that reserved for popes and cardinals. Paul II made it penal for anyone but cardinals to wear hats of scarlet; compare Roman Ceremonial [3.5.5].
