Medieval shield colors

The colors on medieval shields were not merely decorative; they followed a strict heraldic system that communicated lineages, deeds, and loyalties on the battlefield.

About this subject

In the Middle Ages, shield colors obeyed strict heraldic rules that codified coats of arms and symbols. Tinctures were divided into metals (gold and silver), colors (red, blue, green, black, purple), and furs (ermine and counter-ermine). Each color carried symbolic meanings: red represented courage and blood shed in battle; blue, loyalty and truth; green, hope and joy; black, prudence and mourning; purple, royalty and sovereignty; gold, generosity and nobility; silver, peace and sincerity. A fundamental rule was never to place color over color or metal over metal, ensuring contrast and legibility from a distance.

The production of colors involved natural pigments often imported from distant regions. Blue, for example, came from lapis lazuli stone from Afghanistan or copper carbonate, while red was extracted from cinnabar or kermes, a dried insect. Green used malachite or verdigris; black, charcoal or burnt bone. These pigments were mixed with oil or tempera to fix onto the wood, leather, or metal of shields. Application required skilled painters, often monks or guild craftsmen, and high costs made vivid colors a sign of wealth and power.

Regionally, color preferences varied. In France and England, red and blue were common among the nobility; in the Iberian Peninsula, red and gold echoed the colors of Christian kingdoms. During the Crusades, Byzantine and Islamic influences brought new palettes, such as intense greens and purples. Color usage also changed over time: in the 12th century, sober tones predominated; in the 14th and 15th centuries, with the flourishing of heraldry, shields became more ornate and complex, incorporating divisions, animals, and geometric figures. The Battle of Agincourt (1415) is an example where the colors of French and English shields were crucial to identifying allies in combat chaos.

Beyond the military field, shield colors had social and legal functions. They identified families in tournaments, seals, and official documents. Even today, many national flags and city coats of arms derive from these medieval schemes. Knowledge of tinctures was passed down through treatises such as John de Bado Aureo's "De Herauldry," which consolidated heraldic rules that persist largely in contemporary ceremonial use.

Frequently Asked Questions

Why were colors important on medieval shields?

Colors on medieval shields were part of heraldry, a system that identified individuals, families, and armies in battles and tournaments. They conveyed messages about lineage, virtues, and loyalty, following strict rules of combination and symbolism.

How were pigments obtained for coloring shields?

Pigments came from natural sources: blue from lapis lazuli or copper carbonate, red from cinnabar or kermes insects, green from malachite, black from charcoal, and white from gypsum. They were ground and mixed with oil or animal glue to adhere to the surface.

Is there a rule for combining colors on a medieval coat of arms?

Yes, the main rule is never to place color on color (e.g., blue on red) nor metal on metal (gold on silver). Colors can only be placed on metals, and vice versa, to ensure contrast. This rule is still followed in modern heraldry.
