Black Triangle Sighting in New Jersey on June 28th 2015 – It changed colrs, the object was going west and a second after it was going east

I was on my way home from the beach, it was about 10:50 pm all of a sudden I see an object appear out of nowhere it was a green object then it turned blue, it might have turned purple but im not quit sure after it turned orange and then it turned red as it was changing colors it was moving to the west and after that I didn't see any colors besides 3 red dots that formed a triangle and there was a white light next to it after the red dots and white light appeared instead of going west it was going east, the object did not turn around or make a turn it just went east. I could not believe what I was seeing it all happened in less than 30 seconds after that I tried looking for it but could not find it, it felt like it lasted hours after that I could not described what I have seen I felt like I had anxiety but in a weird way I was shaking I was excited I don't really know how to describe the way I was feeLing, as I was watching I could not stop staring. It was an awesome experience but it was also so unreal.
