A charge that is coloured as it naturally appears is blazoned "proper" (Fr. ""), or "the colour of nature". Strictly speaking, "proper" is not a tincture in itself, and if, as is sometimes the case, a charge is meant to be depicted in particular colours that are not apparent from the word "proper" alone, they may be specified in whatever detail is necessary. Certain charges are considered "proper" when portrayed with particular colours, even though a range of different colours is found in nature; for instance, a popinjay "proper" is green, even though wild parrots occur in a variety of colours. In some cases, a charge depicted in a particular set of colours may be referred to as "proper", even though it consists entirely of heraldic tinctures; a rose "proper", whether red or white, is barbed "vert" and seeded "or".
