Generally, adult coyotes (including coywolf hybrids) have a sable coat color, dark neonatal coat color, bushy tail with an active supracaudal gland, and a white facial mask. [12] Albinism is extremely rare in coyotes. Out of a total of 750,000 coyotes killed by federal and cooperative hunters between March 1938 and June 1945, only two were albinos.
From velvety purples to fiery reds, many people can see a spectrum of vivid colors via the human eye. Others, however, may have limited hue perception due to certain conditions.. Animals, on the ...
Birds, too, can see into the ultraviolet (300–400 nm), and some have sex-dependent markings on their plumage that are visible only in the ultraviolet range. [44] [45] Many animals that can see into the ultraviolet range, however, cannot see red light or any other reddish wavelengths. For example, bees' visible spectrum ends at about 590 nm ...

For example, to see "stygian blue": staring at bright yellow causes a dark blue afterimage, then on looking at black, the blue is seen as blue against the black, also as dark as the black. The color is not possible to achieve through normal vision, because the lack of incident light (in the black) prevents saturation of the blue/yellow ...
