I did a day hike from Bear's Den heading south and shortly after getting on the trail, the blazes changed to orange. I know I was still on the AT because there was a metal tube sticking out of the ground indicating it was the AT with the logo on it.

There were also signs on one side indicating that side was private property.

It was just a little confusing because there were white blazes when I first got on the trail. Just curious why these were orange.
