Thought this photo was interesting in regard to camo
 

These turkey hunters are not trying to conceal themselves, but it looks to me that the best match for camo to nature is the hunter on the left. His pants match the rocks. Second place is the match to the turkey wing.

To me, all the other patterns they're wearing would stick out any other place in photo.

Match your surroundings and use 3D camo whenever possible IMO
