Back in the 80's a friend and I worked on trying to develop a new camo pattern. Spent a lot of time researching ungulate eye structure and what deer supposedly can see. Best information came from a professor out at the University of Montana I think it was.
We developed a pattern that had predominantly larger high contrast vertical structure, I think it would have worked quite well had we had the bucks to market it.
But here is the thing, knowing how a deers eye works, tells us nothing about how their brains interpret what they see. That is not possible for us to know. I don't think there has been any comprehensive study done to see what works and what doesn't. If there has and anyone knows of it shout out.

Leonard Lee Rue III wrote a few books on whitetail deer behavior that would be useful.

Penn State has a deer research group that posts monthly or more blogs. Here is one on a deer's vision.

I’m sure it’s like humans, some see better then others. I think also some are better at interpreting what they see as dangerous.

Like others in the natural world, they've evolved to see what they need to see.
Humans don't usually see what they need to see, they see what they want to see.

How a deer interprets what it sees is an evolutionary adaptation that we likely will never understand completely. Like many of the mysteries of nature, we may never fully grasp what they mean, or how certain traits develop in other species. But then, some mysteries retain more interest from us if we don't know what they involve, like why, now and then, Brymesser's cows would all stand and face the same direction in the pasture next to my boyhood home place. I think they did it just to make us kids wonder why. :)))

The attached link is from a Wired to Hunt Podcast. The guest did a good job explaining not only the colors deer see but how they perceive movement.
My summary is they see blue the best and red the worst. They have terrible depth perception and that is why they are always adjusting their head when trying to figure out what you are. They see really well in low light. They are able to process more frames per second than we can.

I always wondered how they can tell what a deer sees? you can not ask them

I don't care. As long at they don't see me hiding in one of my ambush blinds and I use ASAT, and walk by at 15 yds so I can kill them, don't care what they see.

From my experience hunting them for the last 45 years I believe what they see is either already associated with danger, trying to decide if it should be associated with danger or not associated with danger. I believe this true about all prey animals. I think their lives are pretty basic in they need to eat, mate and stay alive.

I agree lv2bohunt. I swear blaze orange doesn't seem to bother them

“I always wondered how they can tell what a deer sees? you can not ask them”
They may be able to tell just by looking at the photoreceptor cells and judge from that, and I expect they might be able to get some electrodes into the vision center of the brain, expose the eyes to different wave-length light sources and see what lights them up. Someone ran a study on Mantis shrimp and found 16 kinds of color receptors, so presumably they can see colors that we can’t even imagine….
Humans generally have 3 kinds (red, blue, green). Most animals seem to have 2, and deer/ungulates apparently don’t have Red receptors. Blaze Orange probably looks like grey. You don’t have to have hunted very long to have had a deer walk right past your blaze orange self.
Then they can look at how densely packed the rods and cones are and get a sense of how high-res their vision can be. A lot of animals - reptiles in particular - have pretty poor resolution and won’t recognize a food item until it moves. But I have read somewhere that cats are much the same.
And we all know that Cervid brains are wired to pay attention to movement. Like when you see the film of a lion stalking an animal seemingly without a shred of cover, but they don’t get seen until they get seen MOVING.
No wonder the first thing most prey species do when they detect an unknown is to freeze in place.

Sometimes they can't see very well at all.

Funny you mention this. Just today I took my red/black wools coats (both large pattern) and my ASAT and my blaze orange stocking cap and my gray wool crusher outside. I looked at them through my cell phone with the photo set to black and white. The wool coats and the ASAT look almost the same. The blaze orange and the gray wool looked like a light shade of gray. However, I'm still not sure what deer really see!

I think it's interesting to try and figure these sort of things out, I've read the Penn state articles , some probably, good information, but probably pretty hard to do a study

Not meaning to change the subject at all, but one thing that I have noticed and wondered about off and on for over 45 years or so, while bow hunting in particular is, due to the fact that I have mostly always hunted farm country and often had to hunt in areas where cattle grazed, the cows would often pick me off out of a tree stand or hiding on the ground, far more often than most deer do.
I suspect they can see far better or in more color than a deer. Either that or cows just recognize the human form quicker because they are around people more or something.

They see everything we see, they perceive things differently than we do.
