Purple is a rare colour in early rolls of arms. In heraldic terms it is referred to as “purpure.” This is the traditional colour of kings and royalty, and therefore, signifies justice and majesty. In engravings, it is expressed by lines in bend sinister, or slanting to the left.
An orange is the name given to a tawny roundle, a roundle being any circular charge of colour or metal. It is supposed to represent a tennis ball.

Blue was called "azure" by heralds, and represents the colour of an eastern sky on a clear day. It also corresponds to the metal tin.

Black, the coldest of the colours, corresponds to lead. Black, or "sable," is symbolic of sadness. It also corresponds with winter and is a humble color, suitable for the deeply religious. It denotes the qualities of knowledge, piety, serenity and work. Engravers represent it with numerous horizontal and vertical lines crossing each other.
Green, or in heraldic terms, "vert," signifies felicity and pleasure. It was symbolic of joy, youth and beauty. Green was also associated with the spring.
