Cinereous
Cinereous is a colour, meaning ashy grey in appearance, either consisting of or resembling ashes, or a grey colour tinged with coppery brown. It is derived from the Latin cinereus, from cinis.
The first recorded use of cinereous as a colour name in English was in 1661.Cinereous in nature
Birds
- The colour name cinereous is used especially in the names of birds with ash grey plumage with a slight coppery brown tinge, including the cinereous antshrike, cinereous becard, cinereous bunting, cinereous conebill, cinereous finch, cinereous ground-tyrant, cinereous harrier, cinereous mourner, cinereous-breasted spinetail, cinereous tinamou, cinereous tyrant, cinereous vulture, and cinereous warbling-finch.
- However, the colours of these birds may be brighter to the birds themselves since birds are tetrachromats and can see colours in the ultraviolet range that are invisible to humans, who are trichromats.
