In heraldry, tinctures are the colours. In English heraldry the tinctures comprise two metals, five colours and eight furs. They are symbolised or indicated by dots and lines - a system noted for its convenience and said to have been introduced about 1630 by an Italian named Silvestre de Petrasancta, though some such symbolism has been found predating him. Over the years the method of symbolism evolved, and the modern system was developed around the start of the 18th century.
Each tincture has a name, a title, an abbreviation and a symbolic representation. The two metals are gold, with the title or and the abbreviation or, represented by dots on a white background; silver with the titleargent and the abbreviation arg, which is represented by a plain white surface. The colours are blue, titled azure, abbreviated az and represented by horizontal parallel lines; red titled gules, abbreviated gu and represented by parallel vertical lines; black, titled sable, abbreviated sa and represented by by vertical and horizontal lines crossing each other; green, titled vert, abbreviated vert and represented by parallel lines sloping downward toward the right; purple titled purpure, abbreviated purp and represented by diagonal lines declining from the sinister chief to the dexter base.
The eight furs are not abbreviated, and are known by their titles. They are: ermine, represented by black spots on white; ermines represented by white spots on black; erminois represented by black spots on a background of small black dots on a white background (the symbol for gold); pean represented by small black dots on a white background (the symbol for gold) on black; vair represented by alternating silver and blue spots; countervair; potent represented by alternating silver and blue spots; and counterpotent.
Two other colours were formerly used in English heraldry. These were tenne, an orange-brown colour represented by vertical lines crossing diagonal lines declining from the sinister chief to the dexter base; and murrey or sanguine, a dark crimson red colour represented by diagonal lines from both the dexter and sinister sides crossing each other.
