There is no 1 pattern that does it all. The trouble with the camo on the racks at the hunting store is that it is usually specific to a type of wooodland or terrain. You could spend a small fortune on camo patterns, warm weather, rain, and cold versions of each. I own a couple of these sorts of patterns, but I keep it a mixed forest look, pines, oaks, etc.
Most of my hunting time I spend on the ground. I prefer wearing good military camo instead, you should look at the new stuff that all our branches will soon enough be wearing, it is called Multicam. Google that, look in google images. They also have gone back to the buttons instead of velcro-thank God, the digital camo with velcro closures suck as far as long term durability go. You'll spend $35-45 each for new top and bottom of the Multicam, but it is worth the money. Tough as nails clothing, that you can get dirty, spray bug spray on, etc, and not worry about it.
Deer don't have a lot of color receptors in their eye structures, which means they really don't see a lot of color, nothing like we do. Their eyes are made for gathering light, and noticing movement. You won't stand out like a crow against snow when you wear hunter orange while deer hunting, it is far more important to be still and move as little as possible.
The Swiss military has a couple of autumn camo patterns that use red and yellow along with the other colors, in the right conditions you will vanish when you get 10 feet in to the brush, like when the leaves are all turning color. You might consider those patterns, but they are only good for a few weeks of the fall.
Amazing things will happen to you when you are head to foot in camo and out in the wild.
