Argent

In heraldry, argent () is the tincture of silver, and belongs to the class of light tinctures called "metals". It is very frequently depicted as white and usually considered interchangeable with it. In engravings and line drawings, regions to be tinctured ''argent'' are either left blank, or indicated with the abbreviation '''''ar''.'''

The name derives from Latin ''argentum'', translated as "silver" or "white metal". The word ''argent'' had the same meaning in Old French ''blazon'', whence it passed into the English language.

In some historical depictions of coats of arms, a kind of silver leaf was applied to those parts of the device that were argent. Over time, the silver content of these depictions has tarnished and darkened. As a result, it can sometimes be difficult to distinguish regions that were intended as "argent" from those that were "sable". This leaves a false impression that the rule of tincture has been violated in cases where, when applied next to a dark colour, argent now appears to be sable due to tarnish. Provided by Wikipedia
