Can Deer see blaze Orange?

Yep. If it was all about safety orange pants would be just as good, but you can’t see that when you’re in a vehicle. If blaze orange is so much safer why don’t the wardens wear a orange vest? How about everyone else in the bush? I guess their safety doesn’t matter; but better colour up the guy who actually has the rifle to keep him safe?
I can’t help thinking its more about marking the hunters and knowing which vehicles to stop than keeping them safe. I can drive around the farm for the rest of my life and never see a warden, but put hunting colours on and here come the blinky lights.

Agreed, part of it is about identifying who's hunting. But I think that the blaze is about hunter safety too. especially when you're party hunting or doing a push. You can see orange a mile away in the tree line - red and black plaid? ... not so much.

The big picture, "deer are colour blind". Deer will definately detect a hunter if he moves; and even when he dosen't move.

This is not true. Deer can absolutely see color.

The big difference between their eyes and ours are the number of rods vs cones. Rods do low light vision, cones do color perception. Deer have more rods than we do, so they have better vision at dusk/dawn than us. Humans have 3 sets of cones, and they're roughly attuned to blue, green, and red. Deer lack the cones that detect red, so they only see color on the lower end of the spectrum - purple, blue, green, yellow.
