Argent (Ger. ', ', ', or ') is similarly derived from the Latin "argentum", "silver". Although sometimes depicted as metallic silver or faint grey, it is more often represented by white, in part because of the tendency for silver paint to oxidize and darken over time, and in part because of the pleasing effect of white against a contrasting colour. Notwithstanding the widespread use of white for argent, some heraldic authorities have suggested the existence of white as a distinct heraldic colour.
