metal

In heraldry, metals are fundamental elements used in the design of coats of arms. The two primary heraldic metals are or (gold) and argent (silver). These metals are often represented by the colors yellow and white, respectively.12

Heraldry also utilizes a set of colors, including gules (red), azure (blue), vert (green), purpure (purple), and sable (black). Additionally, there are furs, such as ermine and vair, which have distinctive patterns. A core principle in heraldry is the rule of tincture, which generally prohibits placing a color upon a color, or a metal upon a metal, to ensure visibility.134
