How do you administer, much less score a test for a Doe, or a Buck? (I don’t mean Jane Doe, or Uncle Buck.)
I know what you’re thinking—assuming of course you’re a human of a certain age…
No, I'm not talking about Dr. John Dolittle that venerable Hugh Lofting character; no I'm not talking about Rex Harrison who played Dr. Doolittle in the 1967 musical of the same name. Nor am I talking about Eddie Murphy nor Kyla Pratt who starred in Dr. Dolittle 3 and Dr. Dolittle: Tail to the Chief. (Who knew there were so many Dr. Dolittle films?)
No, I’m not talking about: Polynesia, Gub-Gub, Dab-Dab, Too-Too, Pushmi-pullyu, Tommy, Matthew, nor any of the other characters from the Dr. Dolittle books.
I’m talking about a couple of psychologists (who else?):
I’m talking about Drs. Jay Neitz and Timothy O’Neill. Working at W. L. Gore and Associates (an international company of 8,000 employees—all of whom share the same title: associate) they developed a new digital camouflage:

Which hunter is more invisible? Mimicry camouflage, like the RealTree brand shown at right, can blend in beautifully with the background, especially to human eyes. The designers of Optifade, the new digital camouflage shown at left, say theirs is more effective because it’s specifically calibrated to the deer’s vision and uses large shapes (called a macropattern) to break up the outline of the hunter’s body. (Left: W.L. Gore. Right: RealTree.)
John Tierney wrote about Optifade in an article published in the September 23, 2008 New York Times.
Approximately 30,000 years after hunters took to adorning cave walls with their image of a deer, it occurred to them it might be more productive to consider the deer’s image of a hunter.
This was not an easy task. Deer have not left cave paintings of any humans, much less of hunters in camouflage. Those manly overalls and caps splotched with green leaves and brown branches may have looked invisible in the catalogue and impressed the other humans back at the lodge, but what did the deer think of it? Were they just rolling their eyes at each other?
Eventually, though, a few deer were bribed to reveal their secrets. They were given food pellets in return for taking vision tests. The results were not good news for the camo-clad hunters — but ultimately not really good news for the deer either.
… snipped …
“We can measure in animals anything you can measure in a human being and every bit as accurate,” Dr. Neitz says. “The difference is that a vision test that might take 10 minutes in a human can take six months.” The research revealed that deer vision is a little blurrier than human vision — about 20/40 — and that deer see the world roughly like a human with red-green colorblindness. Their eyes have only two color receptors (unlike the three in the human eye). Fortunately for hunters, they have a hard time seeing blaze orange.

the discussion continues in this September 22nd posting on his blog: TierneyLab:
I’ve never been a hunter, but I’ve always had a sneaking admiration for their camouflage — partly because I love outdoor gear, and partly because I respect anyone so passionate about a quest that he’s willing to put on an otherwise ridiculous uniform.
Now, as I explain in my Findings column, there’s a new type of digital camouflage specifically designed to fool deer’s vision. Called Optifade, it’s being unveiled today by W.L. Gore, the inventor of Gore-Tex. The camouflage was developed under the supervision of two psychologists, Jay Neitz, an animal-vision expert at the Medical College of Wisconsin (whose color-vision laboratory offers some on-line tests for humans), and
Timothy O’Neill, a retired Army lieutenant colonel and a former professor at West Point who has been called the father of digital camouflage.
