Having said that though, the colors are only for our human eyes -- not deer's.
Before I had the resources to have both, I was quite comfortable with my Fall Gray when there was an abundance of foliage in the trees. If you take a photo of either Spring Green or Fall Grayand turn it black and white, you couldn't tell what pattern the wearerhad on. Again, the colors are for us as deer hunters, and turkeys.
I've written it many times, and it always seems to make sense to those who understand it... If Fall Gray is deemed as such an incredible pattern when there's no leaves on the trees (and it universally is), then HOW MUCH better is it going to be by ADDING foliage in between you and your quarry?
Remember, as 99% of us are treestand hunters, our backdrops are just about always those light-colored skies. It's rare that deer will approach every time and allow you to keep that big, beautiful tree trunk behind you the whole time like some company's promotional pics would have you believe!
Deception is a tricky pattern: In some instances, it looks great (think the pic in Cabela's); but I've held plenty of samples in my hand that didn't offer as much contrast -- and with open-concept patterns, it's all about the contrast. Contrast is what breaks up the human outline and differentiates these patterns from those mass-marketed, looks-good-at-arm's-length other ones that blob up past 15 feet. If I were dead-set on buying Deception, I'd have to buy it in person and hand-pick the outfit.
