In heraldry, a stain (sometimes termed stainand colour or staynard colour) is one of a few non-standard tinctures or colours (namely murrey, sanguine and tenné), which are only known to occur in post-medieval heraldry and may be used as part of a rebatement of honour. However, in heraldic practice almost none of these rebatements are in fact found; and in British heraldry the stains find only exceptional use, other than for purposes of livery.[1]
