I am not a hunter so the only reason I sometimes wear anything with any resemblance to 'camo' is because it is hard wearing and cheap and perfect for wear while working outside.
But it seems there are many many designs of camo clothing all competing in the marketplace for the hunter's cash. Generally speaking they all seem to offer the property of hiding the hunter's outline from the wary eyes of the prey.
But at the same time I cannot help but think back to an article in AirGunner by Mr Chillingworth in which he looked at the colour of clothing and declared that a brightly patterned orange outfit he was wearing would appear as good camo to the prey. The prey not having adequate colour vision. So it made no difference whether or not the outfit was orange or a shade of green, the camo effect came from the disruptive pattern not the colour.
So why are there not more brightly coloured camo outfits around?
