Coyote's (dogs) are not completely color blind. However, they do not have the same color vision as humans and it has been noted they cannot tell the difference between red and green. The reason for this is that there are only two kinds of colour receptors in the retinas of their eyes. Humans have three kinds of colour cells, with three different recptor molecules sensitive to blue, greenish-yellow, and red, dogs only have recptors for yellow and greenish-blue.
Canine's eyes also lack another human trait the 'fovea', an area especially dense with detailing-sensing cells. As a result, their detail vision is not as good as ours. But they make up for this by having much better night vision and greater sensitivity to movement.
Coyote's have an acute sense of hearing and smell and the challenge is to lure him into your kill-zone. And precautions in limiting human sent and activity must be observed. Above all... don't eat a bowl of beans the night before a coyoye hunt!
