Context: Externally, Orthodox Jews can be identified by their manner of dress and family lifestyle. Orthodox women dress modestly by keeping most of their skin covered. Additionally, married women cover their hair, most commonly in the form of a scarf, also in the form of hats, bandanas, berets, snoods or, sometimes, wigs. Orthodox men wear a skullcap known as a kipa and often fringes called "tzitzit". Haredi men often grow beards and always wear black hats and suits, indoors and outdoors. However, Modern Orthodox Jews are commonly indistinguishable in their dress from those around them.

Problem: Given the question: Extract the answer to the question from the following context. Question: Why were religious figures like Christ painted red? Context: Red was the color of the banner of the Byzantine emperors. In Western Europe, Emperor Charlemagne painted his palace red as a very visible symbol of his authority, and wore red shoes at his coronation. Kings, princes and, beginning in 1295, Roman Catholic cardinals began to wear red costumes. When Abbe Suger rebuilt Saint Denis Basilica outside Paris in the early 12th century, he added stained glass windows colored blue cobalt glass and red glass tinted with copper. Together they flooded the basilica with a mystical light. Soon stained glass windows were being added to cathedrals all across France, England and Germany. In Medieval painting red was used to attract attention to the most important figures; both Christ and the Virgin Mary were commonly painted wearing red mantles.
