Heraldry
Heraldry is described in English using a specialised jargon called Blazon which is based on French words.  Heraldry uses only bold, bright colors, called tinctures, with special names.  Gold, for instance, is called Or.  This word is often capitalised to distinguish it from the conjunction or.  Silver and white are sometimes treated as different colors, but in English Blazon both are called argent.  Some combinations of colors represent furs, and these have names that are only used in heraldry.  There are a number of geometric shapes, called ordinaries, that are used in heraldry, and each of these has a special name too.  The shield may be divided in a number of ways, usually following the lines of the ordinaries.
