I was told that part of the reasons most states will not agree to blaze orange camo meeting the " standard ", is that the " standard " was set by agreement of a committee from all the states, and the Canadian provinces, as to what color " Blaze orange" actually is. This was for the benefit of outdoor clothing manufacturers so that their products would comply with all the state's laws and all the Canadian Provincial laws and regulations. When "Blaze Orange Camo", came out, the committee could not agree on how much Orange color is needed per square foot, or meter, to satisfy the requirements they previously set. As a result of lack of agreement, Blaze Orange Camo is not allowed as a substitute for solid blaze orange clothing in most states.
There nothing that prevents you from wearing Blaze Orange Camo, however. You just have to wear the solid Blaze orange hat, and vest, in most state over it.
A Blaze orange camo blind would also be legal, as long as you were also wearing the required solid blaze orange vests and hat. Personally, I like to make a ground blind of natural materials, and sit behind it, or inside of the blind wearing my B.O. Vest and hat. I still run some tape around any tree I am near, so that anyone approaching from any direction is alerted that another hunter is present. B.O. is for my own safety, not the safety of other hunters.
