Gold (Or) is used to denote generosity and elevation of the mind. Silver (Argent), the other base metal used in coats of arms, represents peace and sincerity.

Red (Gules in blazon parlance) is used to designate a warrior or martyr. It also represents military strength and magnanimity.

Blue. When blue (Azure) appears on a shield it typically refers to truth and loyalty.

Green (Vert) refers to hope, joy, and loyalty in love.

Black (Sable) has to do with constancy and, when appropriate, grief.

Purple (Purpure) is used to denote things having to do with royalty, majesty, sovereignty, and justice.

These are the primary colors that are found on coats of arms but lots of other colors will be found (e.g. orange…tenne.. having to do with ambition; maroon…murray…refer to one who is patient but victorious in battle, etc.). These colors were developed to suit specific purposes. One would have to examine those circumstances to determine the meaning of the color in a specific coat of arms. The ones described here can be used as general guides for the meaning behind a given coat of arms.
