From vegetable dyes, the woolen threads of the Bayeux Tapestry were dyed in five dominant tones: brick red, green-blue, old gold, olive green, and blue. The embroidery provides a thorough description of everyday life at the time of Duke William of Normandy and depicts buildings, furniture, clothing, tools, weapons, etc. This piece of secular Romanesque art from the Middle Ages has significant documentary value for the knowledge of the Norman and English 11th centuries.
