What ungulates see
Human vision uses full range of colors. Ungulate vision uses shades of yellow, blue and gray only.
Bottom line: Ungulates suffer from red-green colorblindness.
(See Figure 1)
The human's field of view is 120°. The ungulate's field of view is 280° and a simple turn of the head expands its view to 360°.
Bottom line: Ungulates have a wider field of vision.
(See Figure 2)
Mimicry patterns (like those on traditional camouflage) are designed to work at engagement distances of 20 meters or less.
Even high-definition sticks and leaves on mimicry patterns that appear photorealistic on the store shelf, block up into a mass of gray at standard hunting engagement ranges due to a principal known as isoluminence.
Bottom line: Traditional camouflage fails at standard hunting engagement ranges.
