I'm not exactly sure of the color since I am partially color blind. The fireball maintained an almost steady angle above the horizon before going out with no flash or sound. It seemed a little bit slower than many other fireballs that I've seen in the past and I thought it might be an aircraft at first but after a few seconds of observing it, I realized it was indeed much too fast to be an aircraft plus the light was suddenly extinguished after about 3.5 to 4 seconds of observing it.
