A few years back, I saw an article and pictures where a guy did some "field" testing to show what different "camo" looked like when out in the field.
Most of "camo" hunting patterns did not blend well with any of the backgrounds. The camo was really bad when pictures were taken of a hunter up in a tree stand. In a tree stand......the best "camo" to hide the hunter was when he was wearing a old Blue and white coat. Even a red and light color jacket looked better than "camo" patterns.
Some of the hunting clothing is now made with lighter & darker colors....and bigger patterns.....which IMO, are much better.
