I also used to think orange was not required, just ID your target before shooting. Then one day as a teenager hunting with dad, he yelled there's a deer, shoot it. It was running away from us across an open wheat field. I pulled up my rifle, centered my crosshairs on it and was about to squeeze the trigger. Something told me something was wrong and the tan deer was running away oddly. Turns out it was a hunter dressed head to foot in the safari tan hunting clothes running away. Looked exactly like the hind end of a deer running away. Had I been using iron sights, he probably would have taken my bullet that day, luckily the 3x scope was enough. Scared the living hello out of me because he initially looked like a deer even through the scope. So, I definitely feel everyone should be wearing Blaze orange.
