Red and yellow hats in Venetian society

In the 14th century the Venetian government put into law that all Jews coming into the city had to wear a yellow circle on their outermost layer of clothing in order to distinguish the Christians and Jews and further their segregation. After years of Jewish people allegedly not following this law the government replaced the yellow circle on their clothing with a yellow head covering or yarmulke to increase visibility in 1497. The head covering color was supposed to be yellow but many of the Jewish people coming into the city chose to wear red instead, with the exception of those of Levantine origin. While there is no solid proof for the reasoning of this change, many believe it is because of the stigma surrounding the color yellow which was also used to mark pimps and prostitutes. Eventually, in 1738 Venetian government updated the law to officially include the use of red head coverings.[4]

Catholic Church

A zucchetto can be worn by any ordained member of the Roman Catholic Church. The use of these head coverings predates the invention of centralized heating, between that and the tops of their heads being tonsured and the lack of hoods on their capes, the clergymen needed something to keep them warm, now they've become a traditionalized form of dress. The color of a Zucchetto depends on a clergymen's rank in the church:
