The specific color observed in the vestments of Catholic cardinals is, more accurately, Roman purple, a shade that falls closer to fuchsia than a true violet. The choice of this color is deliberate, holding significant symbolic weight within the Church. The garments, including the cassock, zucchetto (skullcap), and biretta (square hat), are all made in this distinctive hue.
Roman purple represents the blood of Christ and the cardinal’s willingness to defend the faith, even to the point of martyrdom. This symbolism harkens back to the early Church, when many Christians faced persecution. The color serves as a constant reminder of the sacrifices made by those who came before and the commitment cardinals make upon entering their high office. Historically, the shade was associated with royalty and power, reflecting the elevated position of cardinals within the hierarchical structure of the Catholic Church.
