Most mammals are colorblind. The blaze orange is used to identify and protect the hunters from the other hunters. In some seasons blaze orange may not be required and then camo gives an advantage such as bow season for deer in some areas. That said, the camo does break up the pattern of your body and helps disguise the hunter even if you are wearing blaze orange on your chest, back and head.
Bears can see Blaze orange just fine ...and it was required for the NJ hunt, but no longer required at the check station so the press probably never saw anyone wearing it.
