Tinctures provide the limited palette of colours and patterns used in heraldry. The use of these tinctures dates back to the formative period of European heraldry, in the twelfth and thirteenth centuries, but the range of tinctures and the manner of depicting and describing them has evolved over time, as new variations and practices have developed. The need to define, depict, and correctly blazon the various tinctures is therefore one of the most important aspects of heraldic art and design.
The colours and patterns of the heraldic palette are divided into three groups, usually known as metals, colours, and furs. In its original sense, tincture refers only to the group conventionally referred to as "colours". But as the word "colour" seems inapplicable to the heraldic furs, and no other term clearly encompasses all three classes, the word "tincture" has come to be used in this broader sense, while "colour" has acquired the more restricted sense originally given to "tincture". Thus, when consulting various heraldic authorities, care must be taken to determine which meaning each term is given.
The basic scheme and rules of applying the heraldic tinctures dates to the formative period of heraldry, during the twelfth and thirteenth centuries. By the time of the earliest coloured heraldic illustrations, in the mid-thirteenth century, the use of two metals, five colours, and two furs had become standardized, and ever since that time, the great majority of heraldic art has employed these nine tinctures.
Over time, variations on these basic tinctures were developed, particularly with respect to the furs, although the authorities differ as to whether these should be considered separate tinctures, or merely varieties of existing ones. Two additional colours appeared, and were generally accepted by heraldic writers, although they remained scarce, and were eventually termed stains, from the belief that they were used to signify some dishonour on the part of the bearer. The practice of depicting certain charges as they appear in nature, termed proper, was established by the seventeenth century. Other colours have appeared occasionally since the eighteenth century, especially in continental heraldry, but their use is infrequent, and they have never been regarded as particularly heraldic, or numbered among the tinctures that form the basis of heraldic design.
In the English-speaking world, heraldic terminology is based largely on that of British armory, which in turn is based on Norman French. With respect to the heraldic tinctures, French heraldry, which is often cited by heraldic authors, uses similar terminology; while German heraldry, also highly influential, uses a different vocabulary; it calls the colours by their everyday names.
