Polychrome is the use of multiple colors in architecture, sculpture, or other art forms. The term comes from Greek words meaning "many colors." Most often it refers to Gothic, Art Nouveau, or Renaissance styles that use varied colors. Examples can be found in churches around Poland, including the Franciscan Church in Opole which contains well-preserved 16th century polychrome paintings and fragments in its chapels and on walls. The Brzeg Polychrome Route also features several medieval churches with rediscovered Gothic-era polychrome artworks.
