I don't leave my body through my head. I go out the side.
Colors are common. Don't worry too much about what you see.
I have had experiences where it felt like i was being pulled out of my body by someone else and experiences where I definitely did the whole thing myself. Common. As to who pulled you... could have been a spirit guide or angel, could have been another person, could have been someone nefarious, etc.
