I've been racking my brain for snakes that it might be; and the only things I can think of that could possibly match that description are Queen snakes, Smooth Green snakes, Rough green snakes, Northern Brown snakes, Eastern Worm snakes, or possibly a Smooth Earth snake. All of which are native to New Jersey and completely harmless.
Keep in mind that depending on the lighting, certain snakes can look slightly different colors, and color/pattern variation can differ to some extent between individual snakes of the same species. :)
Here are pictures of all of the above:

I hope this helps, and if you have any further questions (or none of these seem to be the right snake); please feel free to message me and I will be more than happy to assist you. :)
I've been keeping reptiles (snakes in particular) for over thirteen years.
