Rule of tincture
Rule of color composition in heraldic design / From Wikipedia, the free encyclopedia
The rule of tincture is a design philosophy found in some heraldic traditions that states "metal should not be put on metal, nor colour on colour".[1] Heraldic furs such as ermine and vair, and charges described as "proper", are generally exempt from the rule of tincture.
