Sight of Deer
We live in Montana and, during the hunting season, wear
bright orange as protection against errant hunters. This has prompted us
to wonder if deer can see the orange? Would they be frightened by
it? Are deer colorblind? Thanks for your help. Ken and Barbara Niles,
As far as I understand, deer are colorblind. This is why hunter's
camoflage is red and black - it has the same values of dark and light as
military forest camoflage, so colorblind animals have a hard time seeing
it. Most people, at least those who are not red-green colorblind, can
easily pick out the red color among the forest greens and browns. So as
long as hunters only shoot at what they see, it reduces the chance of being
in the line of fire.
