At the end of the day, buy what you like. You have to live with it for the next XX years. There has been more animals harvested in solid colors than camo. With that said, I do believe camo can only help you out in the field; as long as the pattern somewhat matches your surroundings.
I personally run a camo backpack, camo upper-half and a solid bottom-half. One of the main reasons is that I utilize my clothes for personal use outside of hunting season.
A lot of good points here. I wish I would've read this five years ago.
