Furs may be placed upon either metal or colour, as may also any charge which is termed proper. German heralds describe furs and natural colours as amphibious. It is perfectly legitimate to place fur upon fur, and though not often found, numbers of examples can be quoted; probably one will suffice. The arms of Richardson are: Sable, two hawks belled or, on a chief indented ermine, a pale ermines, and three lions' heads counterchanged. It is also correct to place ermine upon argent. But such coats are not very frequently found, and it is usual in designing a coat to endeavour to arrange that the fur shall be treated as metal or colour according to what may be its background. The reason for this is obvious. It is correct, though unusual, for a charge which is blazoned proper, and yet depicted in a recognised heraldic colour, to be placed upon colour; and where such cases occur, care should be taken that the charges are blazoned proper. A charge composed of more than one tincture, that is, of a metal and colour, may be placed upon a field of either; for example the well-known coat of Stewart, which is: Or, a fess chequy azure and argent; other examples being: Per pale ermine and azure, a fess wavy gules (Broadbent); and: Azure, a lion rampant argent, debruised by a fess per pale of the second and gules (Walsh); but in such coats it will usually be found that the first tincture of the composite charge should be in opposition to the field upon which it is superimposed. For instance, the arms of Stewart are: Or, a fess chequy azure and argent, and to blazon or depict them with a fess chequy argent and azure would be incorrect. When an ordinary is charged upon both metal and colour, it would be quite correct for it to be of either metal, colour, or fur, and in such cases it has never been considered either exceptional or an infraction of the rule that colour must not be placed upon colour, nor metal upon metal. There is one point, however, which is one of these little points one has to learn from actual experience, and which I believe has never yet been quoted in any handbook of heraldry, and that is, that this rule must be thrown overboard with regard to {87} crests and supporters. I cannot call to mind an instance of colour upon colour, but a gold collar around the neck of an argent crest will constantly be met with. The sinister supporter of the Royal achievement is a case in point, and this rule, which forbids colour upon colour, and metal upon metal, only holds with regard to supporters and crests when the crest or supporter itself is treated as a field and _charged with_ one or more objects. The Royal labels, as already stated, appear to be a standing infraction of the rule if white and argent are to be heraldically treated as identical. The rule is also disregarded entirely as regards augmentations and Scottish cadency bordures.
