Why were those colors chosen for the cardinals?

The colors chosen for cardinals, primarily red and yellow, have deep theological and symbolic significance. Red represents the blood of Christ and the sacrifice of martyrs, reflecting the cardinals' role in the Catholic Church as leaders and spiritual guides. Yellow or gold accents symbolize the divine light and glory of God. Together, these colors convey the cardinals' commitment to faith, authority, and their connection to the Church's mission.
