The middle pic is a true color pic.
The initial green color is thought to be the glow from oxygen in the atmosphere at altitudes above 100 kilometers or so, while sodium atoms and other constituents of the cometary dust grain itself contribute to the orange hues.
I have pretty good color vision, but I have never seen anything but white trails from this shower. The aurora picture below looks realistic in color, although the red is usually more red when there is red at all.
