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 are thought to denote a
rebatement of honour. Almost none of these rebatements are found in fact of heraldic practice, however, and in British heraldry the stains find only exceptional use, other than for purposes of livery.
