RE: Clothing????
Matt, the human eye has red, green and blue cones in it. In a deer the red cone is absent, so they see colors suchs as red, orange, brown,etc as a yellow shade. Deer do not filter Blue/UV light like a human, thus why many books, mags or hunters say make sure to wash hunting clothes in UV Killer or detergent that doesn't use UV Brighters in it. All most all commericial laundry detergent (Tide, etc) has brighteners added to make your clothes look clean and shiny after washing. In daylight they see some colour but in low light/night they see black and white...paying particular attention to blue light or UV light as they appear glowing to their eyes. Ever go into a bar or dance where it is dark and UV light is used, only to look at a black or dark blue shirt with little white specs glowing off it...most likely lint from the dryer. How about the stark white shirt that seems to glow bright blue...imagine that without the light and you now know how deer see UV! Deer have incredible depth perception, being they see many colours in shades vs actual colour they can distinguish objects that appear out of the ordinary. Thus the importance is to break up the outline or remove the "blob" effect. Camo alone will not do this. Being rifle season here we must wear solid colours, while Ml and bow season we can dawn camo clothing. I can honestly say it ain't the thing you have on but how you use the landscape and your movements. Many hunters pick high vantage points to watch large areas or spot n' stalk animals, however if you stand or sit where your outline is contrasted against the skyline game will be able to detect something just ain't right and be alerted to your every move. Once a deer is focused on your position and knows something is their you are in tough! So pick spots that conceal your outline - get into the hill, sit against a large base tree or use brush as backing, just try to become part of the landscape instead of sticking out. Minimize your movements, pan with your eyes and if faced with a deer I never try to give them my whole face or direct eye contact, they will win that battle most everytime.
Have fun and good luck!
