The most extensive use of non-heraldic colours is probably associated with "landscape heraldry", a common feature of British and German armory during the latter part of the eighteenth century, and the early part of the nineteenth. Although rarely used for the field itself, landscapes were often granted as augmentations, typically depicting a fortress successfully captured or defended, or a particular ship, or a battle in which the armiger to whom the augmentation was granted was involved. Such landscapes, usually appearing on a chief, might be blazoned with great particularity as to the things portrayed and the colours used to portray them. Officially, these landscapes appeared on a field of argent, but it was common, and perhaps expected, for the artist to add further details, such as the sky and clouds, by which the field might be wholly obscured. The use of landscapes in heraldry fell out of fashion during the Victorian era, when heraldic scholars and artists began looking to earlier and simpler periods of armorial design for inspiration.
