this might be taking this in a bit of a different direction but, most camo works well in its environment, but since we play in seasonal conditions and changing environment you would need more than one set to achieve the perfect "conditional camo"! most guys that have more than one set are in most cases after the theme, collecting or role play etc.
if you are on a budget or only interested in one set, go Olive Drab, but consider a multi cam dark green, tiger stripe, woodland, digital... effective camo is all about disruptive shape, blending, and not one dimensional.
The best cam and concealment is not to move or move as little as possible, if a person don't believe that! wear a gilly suit a walk around, you will be spotted every time. you could wear black sweat pants and a dark green long sleeve tee shirt, get in the shadows use cover properly and you could use your knife on unsuspecting enemy!
sorry, like I said, took it down a different path
