Purple, -- represented in engraving by diagonal lines declining from the right top to the left base of the escutcheon (or from sinister chief to dexter base).
In heraldry, purpure is a tincture, more or less the equivalent of the colour "purple", and is one of the five main or most usually used colours (as opposed to metals). It may be portrayed in engravings by a series of parallel lines at a 45 degree angle running from upper right to lower left from the point of view of an observer, or else indicated by using purp. as an abbreviation.
